EDAC/skx_common: Allow decoding of SGX addresses

Browse Source 
[ Upstream commit e0d3350778 ]

There are no "struct page" associations with SGX pages, causing the check
pfn_to_online_page() to fail. This results in the inability to decode the
SGX addresses and warning messages like:

  Invalid address 0x34cc9a98840 in IA32_MC17_ADDR

Add an additional check to allow the decoding of the error address and to
skip the warning message, if the error address is an SGX address.
