Dan Carpenter 666e934d74 ptp: fix integer overflow in max_vclocks_store 
[ Upstream commit 81d23d2a24012e448f651e007fac2cfd20a45ce0 ]

On 32bit systems, the "4 * max" multiply can overflow.  Use kcalloc()
to do the allocation to prevent this.

Fixes: 44c494c8e30e ("ptp: track available ptp vclocks information")
