Rasmus Villemoes 068b512193 serial: fixup backport of "serial: Deassert Transmit Enable on probe in driver-specific way" 
When 7c7f9bc986 ("serial: Deassert Transmit Enable on probe in
driver-specific way") got backported to 5.15.y, there known as
b079d37752, some hunks were accidentally left out.

In fsl_lpuart.c, this amounts to uart_remove_one_port() being called
in an error path despite uart_add_one_port() not having been called.

In serial_core.c, it is possible that the omission in
uart_suspend_port() is harmless, but the backport did have the
corresponding hunk in uart_resume_port(), it runs counter to the
original commit's intention of

  Skip any invocation of ->set_mctrl() if RS485 is enabled.

and it's certainly better to be aligned with upstream.

Fixes: b079d37752 ("serial: Deassert Transmit Enable on probe in driver-specific way")
