libpayload: Fix unaligned buffer logic in default_memset

Fix an issue when setting an unaligned buffer where n is less
than the difference of the rounded up pointer and the pointer.
This was identified where n=1 was passed.  n was decremented
once, as expected, then decremented again after the while()
evaluated to false.  This resulted in a new n of 4GB.
