[PATCH 3.8 63/91] target/pscsi: fix return value check

[Kamal Mostafa]

3.8.13.13 -stable review patch.  If anyone has any objections, please let me know.

------------------

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.
