cfi_flash: fix bug with flash banks with different sector numbers
The function find_sector() does not take into account if the flash bank
has changed since the last call. This could lead to illegal accesses inside
and beyond the flash_info_t info strcture. For example if the current
flash bank has less sectors than the last used flash bank.
This patch adds two cheks. One that insures, that the current sector does
not exceed the allowed maximum (which is always a good idea). And one that
checks if the current access is to the same flash bank as the last access.
If not, the search loop will start with sector 0.
