mtdoops: fix the oops_page_used array size
commit 556f063580db2953a7e53cd46b47724246320f60 upstream.
The array of unsigned long pointed by oops_page_used is allocated
by vmalloc which requires the size to be in bytes.
BITS_PER_LONG is equal to 32.
If we want to allocate memory for 32 pages with one bit per page then
32 / BITS_PER_LONG is equal to 1 byte that is 8 bits.
To fix it we need to multiply the result by sizeof(unsigned long) equal to 4.
