firewire: test: Fix potential null dereference in firewire kunit test
[ Upstream commit 352fafe97784e81a10a7c74bd508f71a19b53c2a ]
kunit_kzalloc() may return a NULL pointer, dereferencing it without
NULL check may lead to NULL dereference.
Add a NULL check for test_state.
Fixes: 1c8506d62624 ("firewire: test: add test of device attributes for simple AV/C device")
