USB: serial: xr: fix B0 handling
Fix up B0 handling which should leave the baud rate unchanged and
specifically not report back a non-B0 rate when B0 is requested; must
temporarily disable hardware flow control so that RTS can be deasserted;
and should reassert DTR/RTS when moving from B0.
Fixes: c2d405aa86b4 ("USB: serial: add MaxLinear/Exar USB to Serial driver")
