hwmon: (smsc47m1) Fix compiler warning

Some configurations produce the following compiler warning:

drivers/hwmon/smsc47m1.c: In function 'sm_smsc47m1_init':
drivers/hwmon/smsc47m1.c:938: warning: 'address' may be used uninitialized in this function

While this is a false positive, it can easily be fixed by overloading the return
value from smsc47m1_find with both address and error return code (the address
is an unsigned short and thus never negative). This also reduces module size by
a few bytes (46 bytes for x86_64).
