qcacmn: Hold lock for entire nbuf debug iteration
Hold a spinlock for the entire iteration of the nbuf map/unmap
hashtable. This prevents invalid list/memory access issues in case of a
race with an unmap operation. This also trades list/memory safety for
the chance to watchdog bite while printing. Since we are about to panic
anyway, the worst case is manually loading the memory dump to inspect
the contents of the map/unmap hashtable.
