mec1308.c: Untangle successful vs failed init paths

Label mec1308_init_exit now serves as failed init path, it does
cleanup and returns 1, so it is renamed into init_err_exit.

Since all error paths return 1, and successful init is separated
from failure, there is no need to have ret variable anymore.
