Subject: RDMA/cxgb3: Don't crash kernel just because IDR is full
Patch-mainline: v4.18-rc1
Git-commit: cd13a399e66c1b9b039064e8aa2f959eb90d6947
References: bsc#1103992 FATE#326009

cxgb3 driver properly handles errors returned by IDR, so there is no
need to have special case (kernel crash) just because IDR is full.
