Subject: [PATCH] drivers: w1: remove unused inten variable

The following compilation warning shows up when compiling
with W=1.

drivers/w1/masters/ds1wm.c: In function ‘ds1wm_probe’:
drivers/w1/masters/ds1wm.c:512:5: warning: variable ‘inten’ set but not used [-Wunused-but-set-variable]
  u8 inten;
     ^~~~~

Fixed by removing the variable.
