[PATCH V2] nvme: fix multiple ctrl removal scheduling

[Sagi Grimberg]

> 
> V2: 1. Use cancel_work_sync instead of introducing new state (Sagi)
>      2. Skip using NVME_CTRL_SCHED_RESET state (Sagi)
> V1: nvme_probe set RESETTING state and check for NVME_CTRL_RESETTING
>      state in nvme_should_reset instead of work_busy (hch)

This type of information should come after the '---' separator
so git history won't keep it forever.
