John Hubbard f78cdbd75a rds: fix crash in rds_info_getsockopt() 
The conversion to pin_user_pages() had a bug: it overlooked
the case of allocation of pages failing. Fix that by restoring
an equivalent check.

Reported-by: syzbot+118ac0af4ac7f785a45b@syzkaller.appspotmail.com
Fixes: dbfe7d7437 ("rds: convert get_user_pages() --> pin_user_pages()")
