Provide CoreSight abort debug api to stop the active trace sink
from any context. This is a best effort api that can be used to
abruptly stop and disable the current trace sink from anywhere
in the kernel to avoid tracing and hence polluting the trace data

Have maximum blocking time for shutdown operation as DISCONNECT_TIMEOUT.
During this period when SCO connection closes, the userspace will be
updated on the close operation. Existing approach of immidiate return
on shutdown call can cause synchronization issues on SCO state between
kernel and userspace. This happens when disconnect operation takes
more time at kernel space.

When the fault injection framework introduces an error to the data
block, the current code queries the SD card to find the number of
blocks actually programmed. This value would be as requested by the
generic block layer. So the entire request would be completed.
Say, request 0 is pulled from queue and submitted. When this is being
processed, request 1 is pulled from queue and prepared. Request 0
though is successful, fault-injection framework injects an error
and modifies the bytes_xferred variable to a random value less than
requested transfer. Request 1 is not processed and during the handling
of error, the SD card is queried for the actual bytes programmed. This
would be the correct value. Thus blk_end_request would complete
this request and the control would return to fetch request 2. In this
process, request 1 is not processed at all and the application waits
indefinitely for request 1 to be processed. No further requests are
issued to the queue.
This patch identifies, if the fault injection-framework has inserted an
error to this request and doesn't query the card and uses
bytes_xferred to complete the request.
