In commit 5b9fedb31e47 ("quota: Disable quotactl_path syscall") Jan Kara
disabled quotactl_path syscall on several architectures.
This commit disables it on all architectures using unified list of
system calls:
- arm64
- arc
- csky
- h8300
- hexagon
- nds32
- nios2
- openrisc
- riscv (32/64)

I don't have any other fixes for 5.13 at the moment, so I would prefer it if
you could pick it up.

OK, I want this to make it for rc7 so I've pulled this patch to my tree and
will push it to Linus in a few days.
