hwmon: (w83795) Silent false warning from gcc
The code triggers a false warning with older versions of gcc:
w83795.c: In function 'w83795_update_device':
w83795.c:475: warning: 'lsb' may be used uninitialized in this function
I admit that the code is a little tricky, but I see no way to write it
differently without hurting performance. So let's just silent the
warning with a needless initialization.
