[LU-19072] Don't crash in proc_lnet_nis() is ni_status is NULL

Description

When reading LNet tunables, ni_status can be NULL. This triggers an LASSERT() rather than gracefully handling it. Instead, don't crash. Remove the LASSERT().

lnet_ni_get_status_locked() already handles a NULL ni_status. While it's questionable whether ni_status == NULL should be LNET_NI_STATUS_UP or LNET_NI_STATUS_DOWN, it definitely should not crash.
