Subject: libceph: drop ->monmap and err initialization
Git-commit: a341131eb31e55c31f61c038f152a66634d16095
Patch-mainline: v5.16-rc1
References: jsc#SES-1880

Call to build_initial_monmap() is one stone two birds.  Explicitly it
initializes err variable. Implicitly it initializes ->monmap via call to
kzalloc().  We should only declare err and ->monmap is taken care of by
ceph_monc_init() prototype.
