Pavel Tatashin 3d375d7859 mm: update callers to use HASH_ZERO flag 
Update dcache, inode, pid, mountpoint, and mount hash tables to use
HASH_ZERO, and remove initialization after allocations.  In case of
places where HASH_EARLY was used such as in __pv_init_lock_hash the
zeroed hash table was already assumed, because memblock zeroes the
memory.

  Mountpoint-cache hash table entries: 16777216
