protocol/server: reflect lru limit in inode table also
Upon reconfigure, when lru limit of the inode table is changed,
the new value was just saved in the private structure of the
protocol/server xlator and the inode table used to have the older
values still. A brick start was required for the changes to get
reflected. To handle it, traverse through the xlator tree and check
whether a xlator is a bound_xl or not (if it is a bound_xl it would
have its itable pointer set). If a xlator is a bound_xl, then get
the inode table of that bound_xl and set its lru limit to new value
given via cli. Also prune the inode table so that extra inodes are
purged from the inode table.
