afs: Fix key leak in afs_release() and afs_evict_inode()
Fix afs_release() to go through the cleanup part of the function if
FMODE_WRITE is set rather than exiting through vfs_fsync() (which skips the
cleanup). The cleanup involves discarding the refs on the key used for
file ops and the writeback key record.
Also fix afs_evict_inode() to clean up any left over wb keys attached to
the inode/vnode when it is removed.
Fixes: 5a8132761609 ("afs: Do better accretion of small writes on newly created content")
