[PATCH net-next] net: mana: remove unreachable dead code in mana_bpf()

["Muhammad Falak R Wani" <falakreyaz@gmail.com>]

mana_bpf() declares an uninitialized 'ret' and falls through to a
trailing 'return ret;' after a switch statement whose every case
(XDP_SETUP_PROG and default) already returns unconditionally. This
statement is therefore unreachable dead code left over from an
earlier refactor, and it would return an uninitialized value if it
were ever reached.

Drop the unused variable and the unreachable return.
