treewide: fix hex2dec conversion for MAC address checksum offset
If chksum_offset is converted by $(($...)) at the beginning, the check [ -n "$chksum_offset" ] will always return true, as the conversion yields "0" for an empty argument, and [ -n "0" ] is true. With this patch, the variable is not converted before the check, but only when it's used in dd. No conversion is done for use in hexdump, as this can deal with hex value offsets. Fixes: b133e466b08e ("treewide: convert WiFi caldata size and offset to hexadecimal") Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
