'bm_mc_init' only return 0, but the function whicl calls int
check the negative ret, and this is redundant.

This patch fixed it by not checking the return value.

As I understand compiler can do it for you and there is no
point to break the code in the case of future changes if
bm_mc_init() starts to return errors.

Agreed, this patch can be abandoned.
