btrfs: remove redundant parameters from btrfs_bio_alloc

Browse Source 
All callers pass gfp_flags=GFP_NOFS and nr_vecs=BIO_MAX_PAGES.

submit_extent_page adds __GFP_HIGH that does not make a difference in
our case as it allows access to memory reserves but otherwise does not
change the constraints.
