[dpdk-dev] [PATCH 1/3] net/cxgbe: init data value before reading seeprom

[Emmanuel Roullit]

data value could have been garbage if VPD access timed out for VPD read
request could not been issued.

Found with clang static analysis:
drivers/net/cxgbe/base/t4_hw.c:1577:22:
warning: The left operand of '&' is a garbage value
        } while ((stats_reg & 0x1) && --max_poll);
                  ~~~~~~~~~ ^

Fixes: 17ba077c5c54 ("net/cxgbe: support register dump")
