cfi_flash: use buffer length in unmap_physmem()

While the flash_detect_legacy() of drivers/mtd/cfi_flash.c
feed unmap_physmem() with MAP_NOCACHE as 2nd parameter,
the do_spi_flash_read_write() of common/cmd_sf.c
feed unmap_physmem() with the length of the mapped buffer
as 2nd parameter.

It's apparently a bug, and I personally think the 2nd parameter
should be the length of the mapped buffer.
