crypto: ccp - Fix leaking the same page twice

Commit 551120148b67 ("crypto: ccp - Fix a case where SNP_SHUTDOWN is
missed") fixed a case where SNP is left in INIT state if page reclaim
fails. It removes the transition to the INIT state for this command and
adjusts the page state management.

While doing this, it added a call to snp_leak_pages() after a call to
snp_reclaim_pages() failed. Since snp_reclaim_pages() already calls
snp_leak_pages() internally on the pages it fails to reclaim, calling
it again leaks the exact same page twice.

Fix by removing the extra call to snp_leak_pages().

The problem was found by an experimental code review agent based on
gemini-3.1-pro while reviewing backports into v6.18.y.
