linux/bitmap.h: fix type of nbits in bitmap_shift_right()

Browse Source 
Most other bitmap API, including the OOL version __bitmap_shift_right,
take unsigned nbits.  This was accidentally left out from 2fbad29917.

Fixes: 2fbad29917 ("lib: bitmap: change bitmap_shift_right to take unsigned parameters")
