serial: samsung: Fix possible out of bounds access on non-DT platform
On non-DeviceTree platforms, the index of serial device is a static
variable incremented on each probe. It is incremented even if deferred
probe happens when getting the clock in s3c24xx_serial_init_port().
This index is used for referencing elements of statically allocated
s3c24xx_serial_ports array. In case of re-probe, the index will point
outside of this array leading to memory corruption.
Increment the index only on successful probe.
