[media] vpif_capture: fix return value check in vpif_reqbufs()
Commit Message
From: Wei Yongjun <yongjun_wei@trendmicro.com.cn>
In case of error, the function vb2_dma_contig_init_ctx() returns
ERR_PTR() and never returns NULL. The NULL test in the return value
check should be replaced with IS_ERR().
dpatch engine is used to auto generate this patch.
