usb: gadget: g_dnl: fix g_dnl_set_serialnumber()

instead of only copying if strlen(s) is less than 32 characters, let's
just copy at most 31 characters regardless of the size of
serial#. This will guarantee that we always have a serial number if
serial# environment variable is set to anything.

Note that without a proper serial number, USB Command Verifier fails
our test of Device Descriptor since we will claim to have a serial
number without really providing one when requested.
