Nitin Kumbhar a232eb8d20 gpu: nvgpu: fix PRE31-C violations in wpr/vpr dump

nvgpu_err() macro with a nvgpu_readl() call results in
a volatile access. This violates PRE31-C rule - "Using an
unsafe function-like macro with side effect in argument
nvgpu_readl()" due to side effect of a volatile access.

Fix this by moving nvgpu_readl() calls before nvgpu_err().

The messages log VPR and WPR address info. There are no
known attacks using this info. So it shall be safe to
reveal address info.
