btrfs: allocate btrfs_ioctl_quota_rescan_args on stack

Browse source

Instead of using kmalloc() to allocate btrfs_ioctl_quota_rescan_args,
allocate btrfs_ioctl_quota_rescan_args on stack, the size is reasonably
small and ioctls are called in process context.

sizeof(btrfs_ioctl_quota_rescan_args) = 64
