drm/i915/huc: Fix missing error code in intel_huc_init()
Smatch warns:
drivers/gpu/drm/i915/gt/uc/intel_huc.c:388
intel_huc_init() warn: missing error code 'err'
When the allocation of VMAs fail: The value of err is zero at this
point and it is passed to PTR_ERR and also finally returning zero which
is success instead of failure.
Fix this by adding the missing error code when VMA allocation fails.
