[PATCH] drm/xe: Skip creation of pcode sysfs files when pcode is disabled

[Andi Shyti]

From: Andi Shyti <andi.shyti at linux.intel.com>

Coverity warns that 'cap' may be used uninitialised. If pcode
is disabled there is no need to go through the hassle of a
pcode read or taking a PM reference.

Check skip_pcode early in the function and return if it is set.

No change for platforms where pcode is enabled.
