f2fs: remove unnecessary null checking

When __GFP_DIRECT_RECLAIM (included in both GFP_NOIO and GFP_KERNEL) is
specified, bio_alloc_bioset() never fails to allocate a bio.
Commit 67883ade7a98 ("f2fs: remove FAULT_ALLOC_BIO") replaced
f2fs_bio_alloc() with bio_alloc_bioset(), but null checking after
bio_alloc_bioset() was still left.
