Subject: [PATCH] ibmvnic: stop free_all_rwi on failed reset

References: bsc#1184114 ltc#192237 bsc#1179243 ltc#189290
Patch-mainline: v5.10-rc7
Git-commit: 18f141bf97d42f65abfdf17fd93fb3a0dac100e7

When ibmvnic fails to reset, it breaks out of the reset loop and frees
all of the remaining resets from the workqueue. Doing so prevents the
adapter from recovering if no reset is scheduled after that. Instead,
have the driver continue to process resets on the workqueue.

Remove the no longer need free_all_rwi().
