qcacld-3.0: Set csr_prune_channel_list_for_mode prototype in header file

csr_prune_channel_list_for_mode() is implemented in csr_api_roam.c
but is referenced from both csr_api_roam.c and csr_api_scan.c

Set prototype of csr_prune_channel_list_for_mode in csr_inside_api.h
which is included by both files.
