qcacld-3.0: Add one to vdev max allowed create peer count

In some roaming scenario, the old bss peer was not destroyed before
new bss peer create, so new bss peer fail to attach to vdev because
max allowed create peer for STA vdev is 2 (self peer + bss peer + no
TDLS peer on TDLS disabled platform).

Add one more peer count to vdev max peer count for STA.
It has no impact to memory requirement.
