Subject: [PATCH 090/119] lanplus: Cleanup. Refix 6dec83ff, fix be2c0c4b
This is a cleanup commit.
Commit 6dec83ff removed assignment of `rsp` pointer
in SOL-processing block of ipmi_lan_poll_single(),
but left the check for the pointer validity in place.
Although that has effectively fixed the bug of potentially
accessing the null `rsp` pointer in the `else` block introduced
with be2c0c4b, the resulting if/else looked suspicious and left
and impression that a NULL pointer could still be accessed.
This commit removes the check for `rsp` from the `if`
as it is checked at the start of the function where `rsp`
is initialized (and that is the only place where it is ever changed).
