[PATCH v3 3/9] net/ixgbe/base: correct definition of macro

[Bruce Richardson <bruce.richardson@intel.com>]

The definition of IXGBE_LE32_TO_CPUS macro is meant to modify the value
in place - similar to the le32_to_cpus() macro in kernel. Fixing the
definition allows us to remove some warning flags, and removes the need
for the uintptr_t typecasts.

Fixes: aa4fc14d2cee ("ixgbe: update base driver")
Cc: stable@dpdk.org
