cxgb4: use correct type for all-mask IP address comparison
Use correct type to check for all-mask exact match IP addresses.
Fixes following sparse warnings due to big endian value checks
against 0xffffffff in is_addr_all_mask():
cxgb4_filter.c:977:25: warning: restricted __be32 degrades to integer
cxgb4_filter.c:983:37: warning: restricted __be32 degrades to integer
cxgb4_filter.c:984:37: warning: restricted __be32 degrades to integer
cxgb4_filter.c:985:37: warning: restricted __be32 degrades to integer
cxgb4_filter.c:986:37: warning: restricted __be32 degrades to integer
Fixes: 3eb8b62d5a26 ("cxgb4: add support to create hash-filters via tc-flower offload")
