The commit 0775a9cbc6 ("usbip: vhci extension: modifications
to vhci driver") introduced multiple controllers, and nports as a sys
file, and claimed to read the nports from it, but it didn't.
In addition, the get_nports() has been so wrong that even with 8 port
lines for instance, it gets 7 (I am guessing it is due to a '\n' mess).
Nevertheless, we fix it by reading the nports attribute.

The usbip userspace tools call sprintf()/snprintf() and don't check for
the return value which can lead the paths to overflow, truncating the
final file in the path.
More urgently, GCC 7 now warns that these aren't checked with
-Wformat-overflow, and with -Werror enabled in configure.ac, that makes
these tools unbuildable.
This patch fixes these problems by replacing sprintf() with snprintf() in
one place and adding checks for the return value of snprintf().
