net: ena: use SHUTDOWN as reset reason when closing interface

BugLink: https://bugs.launchpad.net/bugs/1890845
commit c1c0e40b367efc92ad05bb802180817534a32343 upstream.

The 'ENA_REGS_RESET_SHUTDOWN' enum indicates a normal driver
shutdown / removal procedure.

Also, a comment is added to one of the reset reason assignments for
code clarity.
