block: don't set BIO_QUIET for BLK_STS_AGAIN

Browse Source 
Commit abb30460bd ("block: mark bio_wouldblock_error() bio with
BIO_QUIET") added this to suppress buffer_head warnings, but neither
when this commit was added nor now any buffer_head using code actually
ever sets REQ_NOWAIT which can lead to BLK_STS_AGAIN.

Remove the special handling for now.  If we ever plan to use REQ_NOWAIT
for buffer_head based I/O we're better off handling BLK_STS_AGAIN in
the completion handler as it actually needs to retry the I/O as well.
