mptfusion: fix msgContext in mptctl_hp_hostinfo
mptfusion: fix msgContext in mptctl_hp_hostinfo

Hi,

without this patch the istwiRWRequest->MsgContext is always set to zero,
this patch saves the MsgContext in a msgcontext variable and then restores
the value.
Thanks to  David Jeffery who found the issue and did the analysis.
