Subject: [PATCH v3] drivers: staging : wlan-ng : collect return status
 without variable

As caller rdev_set_default_key  not particular about -EFAULT.
We can preserve the return value of prism2_domibset_uint32.

----
Changes in v2:
  - remove  masking of original return value with EFAULT
Changes in v3:
  - merge patch v1 and v2 sothat it can be applied on linux-next
