bcm4908: fix calculation of new cferam index
The arithmetic expansion fails when idx becomes a two digit number. Fix this by relying on expr command. root@OpenWrt:/# echo $(((028 + 0) % 1000)) /bin/ash: arithmetic syntax error root@OpenWrt:/# echo $(($(expr 028 + 0) % 1000)) 28 Fixes: a6a0b252baa6 ("bcm4908: add sysupgrade support") Signed-off-by: Sungbo Eo <mans0n@gorani.run>
