EVM: fix return value check in evm_write_xattrs()
In case of error, the function audit_log_start() returns NULL pointer
not ERR_PTR(). The IS_ERR() test in the return value check should be
replaced with NULL test.
Fixes: fa516b66a1bf ("EVM: Allow runtime modification of the set of verified xattrs")
