Shaohua Li 85968a996b md: using GFP_NOIO to allocate bio for flush request
commit b5e1b8cee7 upstream.

A flush request is usually issued in transaction commit code path, so
using GFP_KERNEL to allocate memory for flush request bio falls into
the classic deadlock issue.

This is suitable for any -stable kernel to which it applies as it
avoids a possible deadlock.
