gpg: Fix printing of pubkey algo in --verbose signature verify.

Browse source 
* g10/sig-check.c (check_signature2): Replace arg PK by R_PK and
change the semantics.  Also clear the other R_ args on function entry,
use gpg_error() and change retturn type to gpg_error_t.
* g10/mainproc.c (do_check_sig): Add arg R_PK.
(list_node): Pass NULL for new arg.
(check_sig_and_print): Rework to make use of the returned PK.

The output

gpg: textmode signature, digest algorithm SHA256, key algorithm rsa2048

showed the pubkey algo of the primary key which was surprising.
Changed to print the algo of the subkey used for verification.
