serial: 8250_omap: Fix gpio check for auto RTS/CTS
There are two checks to see if the manual gpio is configured, but these the check is seeing if the structure is NULL instead it should check to see if there are CTS and/or RTS pins defined. This patch uses checks for those individual pins instead of checking for the structure itself to restore auto RTS/CTS.
