[dpdk-dev] [PATCH v2] ixgbe: disable icc compile warning

[Ferruh Yigit]

icc (icc (ICC) 16.0.1 20151021) is generating following compile error:
"
  CC ixgbe_rxtx.o
  .../drivers/net/ixgbe/ixgbe_rxtx.c(153): error #3656: variable
  "free" may be used before its value is set
                      (nb_free > 0 && m->pool != free[0]->pool)) {
			                         ^
"

Indeed this is a false positive and code is correct.
"nb_free" check prevents the free[] access before its value set.

Disabling this icc warning (#3656) for file ixgbe_rxtx.c.
