qcacld-3.0: Allocate proper size for the lim peer idx pool

Browse source 
In station role, peer idx pool's index 1 is reserved for BSS.
for TDLS the index should start from 2.

Thus for station role if number of supported peer is n, the peer
idx pool size should be n + 2

Thus set peer idx pool size to n + 2 if TDLS is enabled.
