pnfs: track last_offset for layoutcommit

Browse source 
iozone tests were failing intermittently against emc-2 due to out-of-order LAYOUTCOMMITs that both specified new_last_offset

nfs41_open_state now maintains a cached value of the last_offset, and avoids sending it with LAYOUTCOMMIT unless the new last_offset is greater than the cached offset.  this cached value is initialized on open/delegation, and updated on setattr for size
