mtd: gpio_flash: handle case where offset + len exceeds the window size

Fix the bug in handling gpio flash read/write when offset + len
from MTD exceeds the window size

[Brian: made some commentary edits. Also note that the BUG_ON() was
provably false for all non-negative inputs (since x % y <= x), so we
dropped it.]
