>Description:
on a thinkpad A475 with a A12-9800B cpu, after suspend-resume the nvme
admin path no longer works.  eg, 'nvmectl devlist' hangs.  the interrupt
count for this device no longer increases as seen by 'vmstat -i' and 
nvmectl is waiting for the 

upon investigation i noticed that suspend removes the IO queue interrupts
but does not touch the admin queue interrupt.  making it remove/re-add
the admin queue interrupt makes nvmectl work.
>How-To-Repeat:
suspend on a thinkpad A475.
