The CXL driver plans to use cper_print_aer() for restricted CXL host (RCH)
logging. This is not currently possible because CXL is a loadable module
and cper_print_aer() depends on cper_mem_err_unpack() which is not
exported.

Export cper_mem_err_unpack() to enable cper_print_aer() usage in
CXL and other loadable modules.
