Delaying key quotas update when key's refcount reaches 0 in key_put() has been causing some issues in fscrypt testing, specifically in fstest generic/581. This commit fixes this test flakiness by dealing with the quotas immediately, and leaving all the other clean-ups to the key garbage collector. This is done by moving the updates to the qnkeys and qnbytes fields in struct key_user from key_gc_unused_keys() into key_put(). Unfortunately, this also means that we need to switch to the irq-version of the spinlock that protects these fields and use spin_lock_{irqsave,irqrestore} in all the code that touches these fields.
