keys: Fix overwrite of key expiration on instantiation

In the Linux kernel, the following vulnerability has been resolved:

keys: Fix overwrite of key expiration on instantiation

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.

CWE-324 Use of a Key Past its Expiration Date

The product uses a cryptographic key or password past its expiration date, which diminishes its safety significantly by increasing the timing window for cracking attacks against that key.
