[Devel] [PATCH vz7] fuse kio: initialize batch in pcs_map shrinker

[Konstantin Khorenko]

Shinker memory is allocated in process_pcs_init_reply() via kvmalloc()
(thus not zeroed) and "batch" field not initialized later in
pcs_mapset_init(), so fit it and initialize to default batch value.

Fixes: 9623c8c78601 ("fuse kio: Add pcs engine combo v0.8")
