Variable iocnum is assigned a value that is never read, the assignment
and hence the variable are redundant can be removed. Also update the
the comment to reflect the correct name of the variable being updated.
Cleans up clang-scan warning:
drivers/message/fusion/mptctl.c:641:8: warning: Although the value stored
to 'iocnum' is used in the enclosing expression, the value is never
actually read from 'iocnum' [deadcode.DeadStores]
