libceph: use ceph_kvmalloc() for osdmap arrays ...
osdmap has a bunch of arrays that grow linearly with the number of
OSDs. osd_state, osd_weight and osd_primary_affinity take 4 bytes per
OSD. osd_addr takes 136 bytes per OSD because of sockaddr_storage.
The CRUSH workspace area also grows linearly with the number of OSDs.
Normally these arrays are allocated at client startup. The osdmap is
usually updated in small incrementals, but once in a while a full map
may need to be processed. For a cluster with 10000 OSDs, this means
a bunch of 40K allocations followed by a 1.3M allocation, all of which
are currently required to be physically contiguous. This results in
sporadic ENOMEM errors, hanging the client.
Go back to manually (re)allocating arrays and use ceph_kvmalloc() to
fall back to non-contiguous allocation when necessary.
