lib/bitmap.c: fix undefined shift in __bitmap_shift_{left|right}()
commit ea5d05b34aca25c066e0699512d0ffbd8ee6ac3e upstream.
If __bitmap_shift_left() or __bitmap_shift_right() are asked to shift by
a multiple of BITS_PER_LONG, they will try to shift a long value by
BITS_PER_LONG bits which is undefined. Change the functions to avoid
the undefined shift.
