PCI/AER: Update is_internal_error() to be non-static is_aer_internal_error()

Browse Source 
The AER driver includes significant logic for handling CXL protocol errors.
The AER driver will be updated in the future to separate the AER and CXL
logic.

Rename the is_internal_error() function to is_aer_internal_error() as it
gives a more precise indication of the purpose. Make
is_aer_internal_error() non-static to allow for the 2 different CXL
topology error model implementations (RCH and VH) to share this helper.
