chelsio/chtls: fix deadlock issue

In chtls_pass_establish() we hold child socket lock using bh_lock_sock
and we are again trying bh_lock_sock in add_to_reap_list, causing deadlock.
Remove bh_lock_sock in add_to_reap_list() as lock is already held.

Fixes: cc35c88ae4db ("crypto : chtls - CPL handler definition")
