Fix PASS_BY_VALUE issue in options_postprocess_mutate_le()

Fix PASS_BY_VALUE issue in options_postprocess_mutate_le()

Fix issue reported by Coverity:
CID 1641424: Performance inefficiencies (PASS_BY_VALUE)
    Passing parameter ce of type "struct connection_entry"
    (size 208 bytes) by value, which exceeds the low
    threshold of 128 bytes.

Commit 8466c2ca unintentionally introduced a performance
penalty due to passing struct connection_entry 'ce'
by value to options_postprocess_mutate_le().
fix this by passing 'ce' by address.
