platform/x86: samsung-galaxybook: Fix problematic pointer cast
commit d37cd54ebeac37a763fbf303ed25f8a6e98328ff upstream.
A user reported that reading the charge threshold on his device
results in very strange values (like 78497792) being returned.
The reason for this seems to be the fact that the driver casts
the int pointer to an u8 pointer, leaving the last 3 bytes of
the destination uninitialized. Fix this by using a temporary
variable instead.
