[PATCH i-g-t 3/4] tests/kms_dirtyfb: disable psr feature only if psr possible

[Vinod Govindapillai <vinod.govindapillai@intel.com>]

When kms_dirtyfb tests are executed on cases where PSR is not
possible the tests are getting skipped. This is because igt_skip
is use in psr_set function. So avoid calling the psr_disable if
not necessary.
