After patch http://review.whamcloud.com/3446 was committed,
filter_grant_check() would be called a second time if there
was no grant space for the write operation in the first time
it was called.
The issue was that all of the lnb[n].rc values were set to
-ENOSPC inside filter_grant_check() the first time it was
called, but at the second time, although there was some space
and the function returned 0 not -ENOSPC, the lnb[n].rc values
were not reset, all of them were still -ENOSPC, which caused
the assertion failure inside filter_commitrw_write().
This patch fixes the above issue.
