serial: qcom-geni: Fix unbalanced runtime PM resume for no_console_suspend

Browse source

When no_console_suspend is set for the serial console, the system
suspend callback skips pm_runtime_force_suspend() to keep the console
active. The resume callback still unconditionally calls
pm_runtime_force_resume(), which triggers an "Unbalanced
pm_runtime_enable!" warning.

Only force resume when the suspend callback force suspended the device.
