linux/bitmap.h: fix type of nbits in bitmap_shift_right()
[ Upstream commit d9873969fa8725dc6a5a21ab788c057fd8719751 ]
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")
