Subject: net/mlx5: Allocate enough space for the FDB sub-namespaces
Patch-mainline: v4.20-rc1
Git-commit: cc3a4cd3f016a081a29b938f1ad17669bfacc9b2
References: bsc#1103990 FATE#326006

FDB_MAX_CHAIN is three.  We wanted to allocate enough memory to hold four
structs but there are missing parentheses so we only allocate enough
memory for three structs and the first byte of the fourth one.

Fixes: 328edb499f99 ("net/mlx5: Split FDB fast path prio to multiple namespaces")
