[ Upstream commit 23a88ade7131aa259c532ab17685c76de562242b ]

Commit 530ea4219231 ("nfs: Referrals should use the same proto setting
as their parent") encloses the fix with #ifdef CONFIG_SUNRPC_XPRT_RDMA.

CONFIG_SUNRPC_XPRT_RDMA is a tristate option, so it should be tested
with #if IS_ENABLED().

Fixes: 530ea4219231 ("nfs: Referrals should use the same proto setting as t=
heir parent")
