This patch remove three calls to dev_err() from sisusb_probe() as
reporting memory allocation failures is redundant:
- Remove a call to dev_err() that was reporting unsuccesful call to
kzalloc().
- Remove two calls to dev_err() that were reporting unsuccesful calls
to kmalloc().
One call to dev_err() reporting memory allocation is left unchanged as
the last patch of the series removes it.
