LU-2665 mdc: Keep resend FLocks

FLocks requests (particulary F_UNLCKs) can't be trashed
upon comm problems with Server/MDS nor upon kill/exit,
thus we need to keep retry/send.

140 patches were scaned and 49 patches were kept. The first two patches are fixes for mistakes made during the first initial port from Lustre to kernel. The rest are ported patches. Please see if it is OK to send them out. Thanks.
