Intel-SIG: commit e2bb9fab perf/x86/intel/uncore: Fix invalid unit
check
This commit is backported as a fix to SPR PMU uncore support.

-------------------------------------

The uncore unit with the type ID 0 and the unit ID 0 is missed.

The table3 of the uncore unit maybe 0. The
uncore_discovery_invalid_unit() mistakenly treated it as an invalid
value.

Remove the !unit.table3 check.

Fixes: edae1f06 ("perf/x86/intel/uncore: Parse uncore discovery tables")
