fw_printenv and fw_setenv

I've discovered that models WRT1900ACS, WRT1900AC V2 and WRT1200AC have a different mtd mapping for u-boot envars. I'm not sure why but the below change make fw_printenv and fw_setenv work.

Exchanging values 0x20000 and 0x40000 in file /etc/fw_env.config solves the issue for whatever reason 😄

/dev/mtd1 0x0 0x20000 0x40000

WRT1900AC V1:

Increasing the u-boot kernel size envars is only required for the WRT1900AC V1. The rest of the WRT router models u-boot kernel size envars are large enough.
