rust: pci: fix typos in Bar struct's comments

Browse Source 
Fix a typo in the doc-comment of the Bar structure: 'inststance ->
instance'.

Add also 'is' to the comment inside Bar's `new()` function (suggested
by Dirk):
// `pdev` is valid by the invariants of `Device`.

Fixes: bf9651f84b ("rust: pci: implement I/O mappable `pci::Bar`")
