rgw_file: fix hiwat behavior

Removed logic to skip reclaim processing conditionally on hiwat,
this probably meant to be related to a lowat value, which does
not exist.

Having exercised the hiwat reclaim behavior, noticed that the
path which moves unreachable objects to LRU, could and probably
should remove them altogether when q.size exceeds hiwat.  Now
the max unreachable float is lane hiwat, for all lanes.

rgw_file: refcnt bugfixes

This change includes 3 related changes:

1. add required lock flags for FHCache updates--this is a crash
   bug under concurrent update/lookup

2. omit to inc/dec refcnt on root filehandles in 2 places--the
   root handle current is not on the lru list, so it's not
   valid to do so

3. based on observation of LRU behavior during creates/deletes,
   update (cohort) LRU unref to move objects to LRU when their
   refcount falls to SENTINEL_REFCNT--this cheaply primes the
   current reclaim() mechanism, so very significanty improves
   space use (e.g., after deletes) in the absence of scans
   (which is common due to nfs-ganesha caching)

doc: Fixes parameter name in rbd configuration on openstack havana/icehouse

The documentation for using rbd together with openstack havana/icehouse
states that the parameter libvirt_disk_cachemodes should be added to
the nova.conf file. However, this is the only parameter that has no
legacy name with a 'libvirt_' prefix. (See
https://github.com/openstack/nova/blob/icehouse-eol/nova/virt/libvirt/driver.py#L252
for the configuration option)
Thus the configured disk_cachemodes were not applied, defaulting to
no caching.
