host/osmocon: fix setting custom baudrate for CP210x

Sniffing requires higher baudrates, so in serial_up_to_eleven() we
try first to set a non-standard baudrate=406250, which is known to
work well with USB-UART converters based on FTDI's FT232 chip.

Contrary to the FTDI's converters, CP210x based ones cannot be
configured to use a non-standard baudrate directly.  They require
special mappings to be present in the EEPROM, so then using a
setting baudrate=B460800 would actually make it use 406250.

Normally, setting baudrate=406250 should fail for CP210x, so we
fall-back to setting baudrate=B460800 if I_HAVE_A_CP210x is defined.
However, for some weird reason, osmo_serial_set_custom_baudrate()
*succeeds* setting non-standard baudrate=406250, what makes osmocon
unable to communicate with the firmware.

This looks like a regression in libosmocore, so let's try to work
it around by moving the baudrate=406250 setting into the else block.
