USB: serial: mos7840: drop buffer-callback return-value comments
The driver write_room and chars_in_buffer callbacks used to incorrectly
return a negative errno in case they were called with a NULL port
driver-data pointer or if some other always-true sanity checks failed.
The bogus sanity checks were later removed by commit ce039bd4b21f ("USB:
serial: mos7840: drop paranoid port checks") and 7b2faede671a ("USB:
serial: mos7840: drop port driver data accessors") but the
function-header comments were never updated to match.
Drop the outdated return-value comments.
