wlan: Create TDLS timer only if it's not created

TDLS peer timers will be destroyed as part of TDLS exit. In roaming
case there is possibility of TDLS exit won't get invoked, leading to
create one more timer while processing TDLS_ENABLE_LINK and making
current timer pointer as dangling.
Hence create a new timer only if it's not created.
