staging: rtl8192e: Remove one of two checks for hardware RTL8192SE

Check for hardware RTL8192SE is done in function _rtl92e_pci_probe()
directly and also two lines later in function rtl92e_check_adapter().
Remove top level check to increase readability.
This pci_read does not follow a pci_write to ensure data is written to
the device.
