qcacld-3.0: Fix FTM mode malfunction and memory leak

Current driver will create two apdaters in FTM mode, with device_mode
STA and P2P, where STA is incorrect and P2P is unnecessary.
And those types will cause memory leak in
qdf_mem_malloc()/sme_deregister_mgmt_frame(), when unloading driver.

Also, it is improper to fix the interface name to wlan0 for FTM mode,
as some platforms may use different naming rule.

Only create one adapter with FTM mode, with variable interface name.
