[PATCH review for 4.9 34/50] ceph: fix bogus endianness change in ceph_ioctl_set_layout

[Levin, Alexander (Sasha Levin)]

From: Jeff Layton <jlayton@xxxxxxxxxx>

[ Upstream commit 24c149ad6914d349d8b64749f20f3f8ea5031fe0 ]

sparse says:

    fs/ceph/ioctl.c:100:28: warning: cast to restricted __le64

preferred_osd is a __s64 so we don't need to do any conversion. Also,
just remove the cast in ceph_ioctl_get_layout as it's not needed.
