Silvio Gissi e4519a0166 keys: Fix overwrite of key expiration on instantiation
commit 9da27fb65a upstream.

The expiry time of a key is unconditionally overwritten during
instantiation, defaulting to turn it permanent. This causes a problem
for DNS resolution as the expiration set by user-space is overwritten to
TIME64_MAX, disabling further DNS updates. Fix this by restoring the
condition that key_set_expiry is only called when the pre-parser sets a
specific expiry.

Fixes: 39299bdd25 ("keys, dns: Allow key types (eg. DNS) to be reclaimed immediately on expiry")
