Subject: [PATCH 1/2] swsusp: simplify memory_bm_find_bit()

The bit obtained by the function memory_bm_find_bit() is represented
by addr and bit_nr. The callers of memory_bm_find_bit() just use addr
and bit_nr as the arguments of set_bit/clear_bit/test_bit.

This patch simplifies the representation of the obtained bit without
using BM_BITS_PER_CHUNK.
