drivers: modem: Fix compiler warning

Browse source 
When building tests/drivers/build_all/modem on native_posix_64 we get:

	modem_cmd_handler.c:545:9: error: ret may be used
	uninitialized in this function
	[-Werror=maybe-uninitialized]

Fix by adding simple initialization of ret = 0 at start of function.
