uboot-envtools: Fix syntax on number of sectors

Browse Source 
ProblemStatement: On EAP104, "fw_setenv" fails with the error "MTD erase error on /dev/mtd10: Invalid argument"
RootCause: uboot-envtools expects hex format for the number of sectors while the config file (/etc/fw_env.config) contains a decimal number format for the number of sectors. This leads to out-of-boundary size calculation within the function "environment_end()".
Solution: Update the scripts to write a hex value instead of a decimal value in the config file.

Reference for the expected format from the config file: Please check the function "get_config" in the file "fw_env.c", where the function uses sscanf to read the parameters from the config file.

Fixes: WIFI-12189
