[XFS] Make growfs work for amounts greater than 2TB
The free block modification code has a 32bit interface, limiting the size the filesystem can be grown even on 64 bit machines. On 32 bit machines, there are other 32bit variables in transaction structures and interfaces that need to be expanded to allow this to work.
