[dpdk-dev] [PATCH v4 1/4] eal/arm64: remove the braces {} for dmb() and dsb()

[Jia He <hejianet@gmail.com>]

for the code as follows:
if (condition)
	rte_smp_rmb();
else
	rte_smp_wmb();
Without this patch, compiler will report this error:
error: 'else' without a previous 'if'

Fixes: 84733fd0d75e ("eal/arm64: fix memory barrier definition")
