[lm-sensors] PATCH: f71882fg: fix fan_to/from_reg prototypes

Hi Jean,

The RPM after conversion from / before conversion to a register value can be
much more then 65535 (up to 1500000), so putting this into an u16 can cause
overflows. This changes the functions to use an int to store / get RPM instead.

Regards,

Hans
