perf/x86/intel/uncore: Fix iounmap() leak on global_init failure
Kernel test robot reported:
Unverified Error/Warning (likely false positive, kindly check if
interested):
arch/x86/events/intel/uncore_discovery.c:293:2-8:
ERROR: missing iounmap; ioremap on line 288 and execution via
conditional on line 292
If domain->global_init() fails in __parse_discovery_table(), the
ioremap'ed MMIO region is not released before returning, resulting
in an MMIO mapping leak.
Fixes: b575fc0e3357 ("perf/x86/intel/uncore: Add domain global init callback")
