qcacld-3.0: Acquire SME lock before csr_roam_offload_scan from SME

In a scenario where the below two HDD commands from different threads
being processed,
1. Disconnect which does an RSO Stop and free the pCurRoamProfile
2. Set Blacklist BSSID which does and RSO Update and accessed
the pCurRoamProfile
pCurRoamProfile is accessed in the function csr_roam_offload_scan
after is freed from the other context.
The Disconnect command from HDD is protected under the global SME lock,
however, the set blacklist BSSID path is not protected under SME lock.
There are multiple instances where csr_roam_offload_scan is called
without the SME lock which could lead to similar issues.

Acquire SME lock before csr_roam_offload_scan from callers in
SME/HDD which can be from other threads.
