tests/kms_psr_sink_crc: test even if PSR is disabled by default

Browse Source 
Use the igt_set_module_param_int() call to enable it, then restore the
previous value after we are done testing.

With this, we can change the psr_enabled() function to psr_possible():
the only requirement should be that we have a PSR capable sink. The
test should now be able to make "Source_OK" and "Enabled" become true
whenever it wants.
