afs: Fix oops in afs_unlink_writeback
I'm seeing the following oops when testing afs:
Unable to handle kernel paging request for data at address 0x00000008

afs_write_begin hits an error and calls afs_unlink_writeback. In there
we do list_del_init on an uninitialised list.
The patch below initialises ->link when creating the afs_writeback struct.
