[PATCH net-next 2/2] cxgb4: properly initialize variables

[Rahul Lakkireddy]

memset variables to 0 to fix sparse warnings:

drivers/net/ethernet/chelsio/cxgb4/cxgb4_cudbg.c:409:42: sparse: Using
plain integer as NULL pointer

drivers/net/ethernet/chelsio/cxgb4/cudbg_zlib.c:43:47: sparse: Using
plain integer as NULL pointer

Fixes: ad75b7d32f25 ("cxgb4: implement ethtool dump data operations")
Fixes: 91c1953de387 ("cxgb4: use zlib deflate to compress firmware dump")
