qcacmn: Fix TDLS set state cmd sequence in concurrent TDLS connections

TDLS set state cmd to firmware is going out of sequence, if STA
is disconnected, when concurrent TDLS connections are active.
This out of sequence causes crash in the firmware.
Fix the out of sequence issue, by grouping all the TDLS delete
peer commands into one single command.
