mec1308.c: Untangle successful vs failed init paths

Label mec1308_init_exit now serves as failed init path,
it does cleanup and returns 1.

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

TEST=builds and ninja test from 51487
BUG=b:185191942
