Sungbo Eo 4607f55439 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
