r8152: reduce the control transfer of rtl8152_get_version()

Reduce the control transfer by moving calling rtl8152_get_version() in
rtl8152_probe(). This could prevent from calling rtl8152_get_version()
for unnecessary situations. For example, after setting config #2 for the
device, there are two interfaces and rtl8152_probe() may be called
twice. However, we don't need to call rtl8152_get_version() for this
situation.
