mtd-utils: fix wrong format specifiers on mips32

This patch fixes the follwing compiler warnings:

flash_erase.c: In function 'show_progress':
flash_erase.c:56:22: warning: format '%lx' expects argument of type 'long unsigned int', but argument 3 has type 'off_t {aka long long int}' [-Wformat=]
  bareverbose(!quiet, "\rErasing %d Kibyte @ %"PRIxoff_t" -- %2i %% complete ",
                      ^
./include/common.h:81:10: note: in definition of macro 'bareverbose'
   printf(fmt, ##__VA_ARGS__);

which are linked to the following buggy numerical output:

Erasing 128 Kibyte @ 0 -- 917504 % complete flash_erase:  Cleanmarker written at 0
Erasing 128 Kibyte @ 0 -- 1048576 % complete flash_erase:  Cleanmarker written at 0
