Revision 1901937

Remove the use of the ERR_GET_FUNC() macro.

The ERR_GET_FUNC() macro was removed in OpenSSL 3.0 [1]:

[[[
Removal of function code from the error codes

The function code part of the error code is now always set to 0. For that
reason the ERR_GET_FUNC() macro was removed. Applications must resolve the
error codes only using the library number and the reason code.
]]]

Remove its two current usages since there is no replacement for this concept in
the newer versions of OpenSSL.
