[PATCH i-g-t v1 1/1] tests/kms_cursor_legacy: don't inhibit pipe CRC calculation

[Michał Grzelak]

Running either flip-vs-cursor-busy-crc-(legacy|atomic) subtest from
kms_cursor_legacy results in entering PSR1 after the test. Even with
PSR2 enabled panel, it is impossible to switch to PSR2 via
i915_edp_psr_debug. Kernel does so because it prevents inhibiting pipe
CRC calculation which is allowed in PSR1 but prohibited in PSR2.
Therefore subtests from kms_psr testing PSR2 feature (e.g. psr2-no-drrs,
psr2-primary-blt etc.) are failing after running any of those
kms_cursor_legacy subtests.

Restore enabling Panel Replay Selective Update by cleaning pipe CRC
calculation after running the subtest.
