ratelimit: convert flags to int to save 8 bytes in size

Browse Source 
Only bit 1 is used, making an unsigned long a total overkill.

This brings it from 40 to 32 bytes, which in turn shrinks user_struct from
136 to 128 bytes.  Since the latter is allocated with hwalign, this means
the total usage goes down from 192 to 128 bytes per object.

No functional changes.
