[PATCH 2/5] hw/nvram/xlnx-bbram: More idiomatic and simpler error reporting

[Markus Armbruster <armbru@xxxxxxxxxx>]

bbram_bdrv_error() interpolates a "detail" string into a template with
error_setg_errno(), then reports the result with error_report().
Produces error messages with an unwanted '.':

    BLK-NAME: BBRAM backstore DETAIL failed.: STERROR

Replace both calls of bbram_bdrv_error() by straightforward
error_report(), and drop the function.  This is less code, easier to
read, and the error message is more greppable.

Also delete the unwanted '.'.
