exec: fix writing to MMIO area with non-power-of-two length
The problem is introduced by commit 2332616 (exec: Support 64-bit
operations in address_space_rw, 2013-07-08). Before that commit,
memory_access_size would only return 1/2/4.
Since alignment is already handled above, reduce l to the largest
power of two that is smaller than l.
