cmd: mtdparts: Fix build with option ..._SHOW_NET_SIZES

That option is currently not used by any defconfig and could not be set
anymore since it became mandatory to used Kconfig when introducing new
options with U-Boot v2016.11 or commit eed921d92348 ("Kconfig: Add a
whitelist of ad-hoc CONFIG options") and commit 371244cb19f9 ("Makefile:
Give a build error if ad-hoc CONFIG options are added").

It was also not considered when fixing build warnings in
commit 39ac34473f3c ("cmd_mtdparts: use 64 bits for flash size,
partition size & offset") and could probably not be compiled anyway
after commit dfe64e2c8973 ("mtd: resync with Linux-3.7.1"), which
renamed some members of struct mtd_info … so it was probably broken
since then, which was U-Boot v2013.07-rc1.

However it still seems to work, see example output below:
