CLEANUP: ssl/cli: use the list of filters in the crtlist_entry

In 'commit ssl cert', instead of trying to regenerate a list of filters
from the SNIs, use the list provided by the crtlist_entry used to
generate the ckch_inst.

This list of filters doesn't need to be free'd anymore since they are
always reused from the crtlist_entry.
