nvmet: make nvmet_wq unbound 



When deleting many controllers one-by-one, it takes a very
long time as these work elements may serialize as they are
scheduled on the executing cpu instead of spreading. In general
nvmet_wq can definitely be used for long standing work elements
so its better to make it unbound regardless.
