[PATCH] [net] ibmvnic: fix dma_mapping_error call

[Desnes Augusto Nunes do Rosario <desnesn@linux.vnet.ibm.com>]

This patch fixes the dma_mapping_error call to use the correct dma_addr
which is inside the ibmvnic_vpd struct. Moreover, it fixes an uninitialized
warning regarding a local dma_addr variable which is not used anymore.

Fixes: 4e6759be28e4 ("ibmvnic: Feature implementation of VPD for the ibmvnic driver")
