iget: stop EFS from using iget() and read_inode()

Browse Source 
Stop the EFS filesystem from using iget() and read_inode().  Replace
efs_read_inode() with efs_iget(), and call that instead of iget().  efs_iget()
then uses iget_locked() directly and returns a proper error code instead of an
inode in the event of an error.

efs_fill_super() returns any error incurred when getting the root inode
instead of EACCES.
