Subject: [PATCH] genalloc: fix allocation from end of pool

bitmap_find_next_zero_area requires the size of the bitmap, we instead
passed the last suitable position.  This made it impossible to allocate
from the end of the pool.

Fixes a regression introduced by 243797f59b748f679ab88d456fcc4f92236d724b
("genalloc: use bitmap_find_next_zero_area").
