GFS2: Userland expects quota limit/warn/usage in 512b blocks

Userland programs using the quotactl() syscall assume limit/warn/usage
block counts in 512b basic blocks which were instead being read/written
in fs blocksize in gfs2. With this patch, gfs2 correctly interacts with
the syscall using 512b blocks.
