mtd: spi-nor: cast to u64 to avoid uint overflows
commit 84a1c2109d23df3543d96231c4fee1757299bb1a upstream.
The "params->size" is defined as "u64".
And "info->sector_size" and "info->n_sectors" are defined as
unsigned int and u16.
Thus, u64 data might have strange data(loss data) if the result
overflows an unsigned int.
This patch casts "info->sector_size" to an u64.
