[PATCH] eal: fix return type of bsf safe functions

[Thomas Monjalon]

In a recent commit, changing return type from int to uint32_t,
I did a last minute change to functions rte_bsf32_safe and rte_bsf64_safe,
because thought they were forgotten.
Actually these functions are returning 0 or 1, so it should be int.
The return type is reverted to the original type for these 2 functions.

Fixes: 4b81c145ae37 ("eal: change return type of bsf/fls functions")
