[PATCH 1/3] wl12xx: fix testmode test/interrogate commands

[Eliad Peller]

fix several issues in testmode test/interrogate commands:
1. check the driver state is not OFF.
2. wakeup the chip from elp (if needed)
3. fix memory leak in wl1271_tm_cmd_interrogate()

[PATCH 2/3] wl12xx: remove redundant commands from plt init

[Eliad Peller]

During plt init we configure some redundant commands,
which are not needed for plt (specifically, we shouldn't
configure any role-specific params, as there are no
active roles). remove them.

[PATCH 3/3] wl12xx: send testmode reply in wl1271_tm_cmd_interrogate

[Eliad Peller]

wl1271_tm_cmd_interrogate creates a reply skb, but doesn't
send it (and thus just leaks it).
Add the missing cfg80211_testmode_reply() call.

Forgot to reply earlier.  But just for the record and consistency, this
series has been applied and pushed.
