Subject: target/pscsi: fix return value check
From: Wei Yongjun <yongjun_wei@xxxxxxxxxxxxxxxxx>
commit 58932e96e438cd78f75e765d7b87ef39d3533d15 upstream.
In case of error, the function scsi_host_lookup() returns NULL
pointer not ERR_PTR(). The IS_ERR() test in the return value check
should be replaced with NULL test.
