net/packet: Add getsockopt support for PACKET_COPY_THRESH
Currently getsockopt does not support PACKET_COPY_THRESH,
and we are unable to get the value of PACKET_COPY_THRESH
socket option through getsockopt.
This patch adds getsockopt support for PACKET_COPY_THRESH.
In addition, this patch converts access to copy_thresh to
READ_ONCE/WRITE_ONCE.
