Fix pointer/int cast in USB devio code, and thus avoid a compiler warning.
A void* data argument passed to bus_find_device() and thence to match_devt()
is used to carry a 32-bit datum. However, casting directly between a u32 and
a pointer is not permitted - there must be an intermediate cast via (unsigned)
long.
This was introduced by the following patch:

usbfs: simplify the lookup-by-minor routines
This patch (as1105) simplifies the lookup-by-minor-number code in
usbfs. Instead of passing the minor number to the callback, which
must then reconstruct the entire dev_t value, the patch passes the
dev_t value directly.
