[PATCH v2 2/2] mac80211_hwsim: set rx_status mactime/flag for wmediumd path

[James Prestwood <prestwoj@gmail.com>]

This patch sets the required rx_status mactime and flags in order for
the parent TSF value to be calculated and sent to userspace. This is
already done elsewhere, but this patch allows this to work for the
wmediumd code path.
