bitmap: fix bitmap_count_one
BITMAP_LAST_WORD_MASK(nbits) returns 0xffffffff when "nbits=0", which makes bitmap_count_one fail to handle the "nbits=0" case. It appears to be preferred to remain BITMAP_LAST_WORD_MASK identical to the kernel implementation that it is ported from. So this patch fixes bitmap_count_one to handle the nbits=0 case.
