qcacld-3.0: Do not reset short preamble support and beacon interval

qcacld-2.0 to qcacld-3.0 propagation

In pe_reset_protection_callback psession's beaconParams struct is
reset to 0 and thus short preamble support being part of this
structure is set to 0. Due to this beacons always have barker
preamble set to 1 even if no non short preamble enabled STA is
connected.

To avoid this do not reset the short preamble support and beacon
interval in psession's beaconParams structure.
