HID: amd_sfh: Handle condition of "no sensors" for SFH1.1

Browse Source 
Based on num_hid_devices, each sensor device registers to HID. If
"no sensors" then amd_sfh work initialization and scheduling
doesn’t make sense and return ENODEV to stop driver probe.
Hence add a check for num_hid_devices to handle special
case in the situation of "no sensors" for SFH1.1.
