qcacld-3.0: Skip starting SAP after channel change if stop BSS in progress

When stop_bss from HDD is received when a SAP channel change request
is currently in progress and channel change response is not yet
received from the FW, the stop_bss would clear the SAP session and
when channel change response is received, we try to start BSS again.
The CSR roam state is also set to JOINING in this case.

As part of start BSS, we queue set key command to SME active command
list. Since the session has been cleared, eWNI_SME_SETCONTEXT_RSP
sent to lim would not be processed in CSR state JOINING leading to set
key command stuck in the active command list.

Do not restart BSS after channel change response if stop BSS is in
progress. Also handle eWNI_SME_SETCONTEXT_RSP and clear the command
queue in CSR Joining state.
