netvsc: use refcount_t for keeping track of sub channels
Rather than a lock and variable, use a refcount_t to keep track
of the number of sub channels. Don't need to wait for subchannels
on device removal since wait was already done in device_add.
Also fix the error handling; don't wait forever in case of
an error on request to create sub channels.
