wpa_supplicant: Remove pending sme-connect radio work

Browse source 
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work is no longer valid.
