[PATCH 2/3] wpa_supplicant: remove pending sme-connect radio work

[Ilan Peer]

If a new connection is attempted while there is a pending
sme-connection radio work, cancel the pending radio work
and continue with the new connection attempt.

This is preferable over rejecting the new work and
continuing with the pending one, as it is possible that the
previous work is no longer valid.
