u_bam_data: Fix issue with RNDIS adaptor enable/disable

Performing RNDIS adaptor disable/enable on host machine sends
PACKET_FILTER with value zero and non-zero respectively. This
is required to handle by disconnecting USB IPA pipe communication
and keeping USB Endpoints active. Hence this change adds required
state machine which allows to peform USB cable disconnect/connect
and RNDIS adaptor disable/enable cases while using RNDIS
functionality.
