gl-mifi-mcu: fix compilation warning for conflicting function

Module called the exit module function "exit", This conflicts with the
stdlib header that use exit() to exit userspace program.

Correctly assign a namespace to these functions. (init and exit)

Fix compilation warning:
warning: the compiler differs from the one used to build the kernel
  The kernel was built by: aarch64-openwrt-linux-musl-gcc (OpenWrt GCC 12.2.0 r21757+608-895f38ca1e) 12.2.0
