xhci: Use %zu for printing size_t type

commit c1a145a3ed9a40f3b6145feb97789e8eb49c5566 upstream.

Commit 597c56e372da ("xhci: update bounce buffer with correct sg num")
caused the following build warnings:

drivers/usb/host/xhci-ring.c:676:19: warning: format '%ld' expects argument of type 'long int', but argument 3 has type 'size_t {aka unsigned int}' [-Wformat=]

Use %zu for printing size_t type in order to fix the warnings.
