net: nixge: Fix error path for obtaining mac address
Fix issue where nixge_get_nvmem_address() returns a non-NULL
return value on a failed nvmem_cell_get() that causes an invalid
access when error value encoded in pointer is dereferenced.
Furthermore ensure that buffer allocated by nvmem_cell_read()
actually gets kfreed() if the function succeeds.
Fixes commit 492caffa8a1a ("net: ethernet: nixge: Add support for
National Instruments XGE netdev")
