[PATCH] drm/xe/hwmon: Use devm_mutex_init()

[Christophe JAILLET]

Use devm_mutex_init() instead of hand-writing it.

This saves some LoC, improves readability and saves some space in the
generated .o file.

Before:
======
   text    data     bss     dec     hex filename
  36884   10296      64   47244    b88c drivers/gpu/drm/xe/xe_hwmon.o

After:
=====
   text    data     bss     dec     hex filename
  36651   10224      64   46939    b75b drivers/gpu/drm/xe/xe_hwmon.o
