swiotlb: remove an unecessary NULL check
Smatch complains here: lib/swiotlb.c:730 swiotlb_alloc_buffer() warn: variable dereferenced before check 'dev' (see line 716) "dev" isn't ever NULL in this function so we can just remove the check. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Christoph Hellwig <hch@lst.de>
