Subject: [PATCH] ipmi: msghandler: ensure error value in rv is being returned on error

From: Colin Ian King <colin.king@...onical.com>

Currently ipmi_set_my_LUN returns 0 instead of -EINVAL if the channel
is out of range.  Fix this by returning the error return rv instead of 0.

Detected by Clang ("variable 'rv' set but not used")

Fixes: 048f7c3e352e ("ipmi: Properly release srcu locks on error conditions")
