[PATCH] bitmap: change return value of rte_bitmap_free

[Stephen Hemminger]

No existing code is checking the return value of rte_bitmap_free
and other functions like rte_free do not return an int.
Change it to just a stub void function.

This was motivated by Coverity warnings about unchecked return
value.
