mtd-utils: nandwrite: prevent 32-bit overflow
For large block- and page-sizes, the multiplication of ebsize_aligned
and pagelen can overflow a 32-bit integer. This overflow can be
prevented by a simple change in order of operations (i.e., do division
first).
Since ebsize_aligned is always a multiple of mtd.min_io_size, this
produces no change in results.
