[PATCH] btrfs: alleviate gfp flags in end_bio_extent_readpage
Use of GFP_ATOMIC is not necessary in this context. This makes
consistent use of GFP_NOFS flag being passed to all funcions like
lock_extent_bits/unlock_extent_bits/set_extent_bit/clear_extent_bit.
(Then the mask argument could be later dropped and the flags used
directly at the allocation calls and not needlessly passed down the
call chain.)
