Alessandro Zanni a0c77e5e3d fs: Fix uninitialized value issue in from_kuid and from_kgid ...

[ Upstream commit 15f34347481648a567db67fb473c23befb796af5 ]

ocfs2_setattr() uses attr->ia_mode, attr->ia_uid and attr->ia_gid in
a trace point even though ATTR_MODE, ATTR_UID and ATTR_GID aren't set.

Initialize all fields of newattrs to avoid uninitialized variables, by
checking if ATTR_MODE, ATTR_UID, ATTR_GID are initialized, otherwise 0.
