block: fix bogus gcc warning for uninitialized var usage
Newer gcc throw this warning: fs/bio.c: In function ?bio_alloc_bioset?: fs/bio.c:305: warning: ?p? may be used uninitialized in this function since it cannot figure out that 'p' is only ever used if 'bs' is non-NULL. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
