hwmon: (dell-smm) Make fan/temp sensor number a u8

Right now, we only use bits 0 to 7 of the fan/temp sensor number
by doing number & 0xff. Passing the value as a u8 makes this
step unnecessary. Also add checks to the ioctl handler since
users might get confused when passing 0x00000101 does the same
as passing 0x00000001.

Tested on a Dell Inspiron 3505.
