HID: Prevent incoming and outgoing SDP collision 

SDP is performed 2 times as part of HID connection in BD stack,
one after successful authentication, and one in HID stack layer
as SDP data is not stored currently in stack. When there is outgoing and
incoming connections, SDP failed message was posted which was resulting
in SDP failure for HID host resulting in improper disconnection of
HID interrupt channel.
