[PATCH 4/4] ACPI / battery: get rid of negations in conditions

[Dmitry Rozhkov <dmitry.rozhkov@linux.intel.com>]

Simple conditions without negations inflict less cognitive load
on readers.

Rework conditional branches not to use negations. Also add braces
around single statement branches where their counterpart else-branches
consist of more than one statement as suggested in the paragraph 3 of
the coding style.
