iwlwifi: fix userspace setting of sleep_level_override
The sleep_level_override debugfs file is used by the user to request a
static power index instead of the dynamic sleep values. Users are expected
to provide value from 1 to 5 as an index or -1 to disable it.
The problem at the moment is that users can also provide 0 to this file
which, together with the value 1, is translated to index 1. This is
confusing and even more so when users write 0 to sleep_level_override and
then read 1 from it afterwards.
Modify checking to treat 0 as invalid.
