Mark Johnston 426682b05a bpf: Fix the write filter for detached descriptors 
A BPF descriptor only has an associated interface descriptor once it is
attached to an interface, e.g., with BIOCSETIF.  Avoid dereferencing a
NULL pointer in filt_bpfwrite() if the BPF descriptor is not attached.

Reviewed by:	ae
Reported by:	syzbot+ae45d5166afe15a5a21d@syzkaller.appspotmail.com
Fixes:	ded77e0237a8 ("Allow the BPF to be select for write.")
