Fabio Scaccabarozzi 590ababea2 Bugfix/fix uio partial copies 
In zfs_write(), the loop continues to the next iteration without
accounting for partial copies occurring in uiomove_iov when 
copy_from_user/__copy_from_user_inatomic return a non-zero status.
This results in "zfs: accessing past end of object..." in the 
kernel log, and the write failing.

Account for partial copies and update uio struct before returning
EFAULT, leave a comment explaining the reason why this is done.
