storage: Fix a vol-clone bug on ppc64

Browse Source 
vol-clone reports out of memory error with disk type on ppc64.

Currently, wbytes is defined as size_t type (8 bytes), but
args's value in ioctl(fd, args..) in kernel is int (4 bytes).
This makes wbytes 2^32 times larger, causing an out of memory error.

This patch changes size_t to int to synchronize with kernel.
