libglusterfs/rbtree: change rbthash_init_table to take no of expected entries in the hash table as argument.
- the expected number of entries is used to create the memory pool of the hash
table. Having constant macro for this purpose is not suitable since different
users of rbtree based hash table store different number of entries in the
table.
