xhci: Use %zu for printing size_t type

Commit 597c56e3 ("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.
