[PATCH AUTOSEL 5.4 093/175] selinux: fix error return code in policydb_read()

[Sasha Levin]

From: Wei Yongjun <weiyongj...@huawei.com>

[ Upstream commit 4c09f8b6913a779ca0c70ea8058bf21537eebb3b ]

Fix to return negative error code -ENOMEM from the kvcalloc() error
handling case instead of 0, as done elsewhere in this function.

Fixes: acdf52d97f82 ("selinux: convert to kvmalloc")
