rhashtable: Allow rhashtable to be used from irq-safe contexts
rhashtable currently only does bh-safe synchronization making it impossible
to use from irq-safe contexts. Switch it to use irq-safe synchronization to
remove the restriction.
v2: Update the lock functions to return the ulong flags value and unlock
functions to take the value directly instead of passing around the
pointer. Suggested by Linus.
