[PATCH v2] eeepc-laptop: clean up control flow in eeepc_acpi_notify

[Frans Klaver]

eeepc_acpi_notify increases the indentation level to a whopping four. If
we revise the conditions a bit, we can reduce that to a more soothing
two and satisfy the indentation guidelines in Documentation/CodingStyle.

Remove an unwanted space while we're in the neighbourhood.
