monitor: Rename+move net_handle_fd_param -> monitor_handle_fd_param

This patch renames+moves the net_handle_fd_param() caller used to
obtain a file descriptor from either qemu_parse_fd() (the normal case)
or from monitor_get_fd() (migration case) into a generically prefixed
monitor_handle_fd_param() to be used by vhost-scsi code.

Also update net/[socket,tap].c consumers to use the new prefix.
