Conserve stack in zfs_setattr()

Move 'bulk' and 'xattr_bulk' from the stack to the heap to minimize
stack space usage.  These two arrays consumed 448 bytes on the stack
and have been replaced by two 8 byte points for a total stack space
saving of 432 bytes.  The zfs_setattr() path had been previously
observed to overrun the stack in certain circumstances.
