P2P: Fix setting of P2P Client Discoverability bit
In the P2P specification v1.1, the P2P Client Discoverability bit is
described in Table 12 "Device Capability Bitmap definition". The table
says "Within a P2P Group Info attribute and a (Re)association request
frame the P2P Client Discoverability field shall be set to 1 when the
P2P Device supports P2P Client Discoverability, and is set to 0
otherwise. This field shall be reserved and set to 0 in all other frames
or uses.". To match with this, filter out P2P Client Discoverability bit
from frames where its use is reserved.
