Re: [PATCH v2] vmxnet3: avoid assumption about invalid dma_pa in vmxnet3_set_mc()

vmxnet3_set_mc() checks new_table_pa returned by dma_map_single()
with dma_mapping_error(), but even there it assumes zero is invalid pa
(it assumes dma_mapping_error(...,0) returns true if new_table is NULL).

The patch adds an explicit variable to track status of new_table_pa.

v2: use "bool" and "true"/"false" for boolean variables.
