Subject: [PATCH 4/7] linux/bitmap.h: fix type of nbits in bitmap_shift_right()

Most other bitmap API, including the OOL version __bitmap_shift_right,
take unsigned nbits. This was accidentally left out from 2fbad29917c98.

Fixes: 2fbad29917c98 (lib: bitmap: change bitmap_shift_right to take unsigned parameters)
