drm/i915/display/psr: Unset enable_psr2_sel_fetch if other checks in intel_psr2_config_valid() fails

[ Upstream commit bb023304 ]

If any of the PSR2 checks after intel_psr2_sel_fetch_config_valid()
fails, enable_psr2_sel_fetch will be kept enabled causing problems
in the functions that only checks for it and not for has_psr2.

So here moving the check that do not depend on enable_psr2_sel_fetch
and for the remaning ones jumping to a section that unset
enable_psr2_sel_fetch in case of failure to support PSR2.

Fixes: 6e43e276
