[PATCH 3/4] platform/x86: fujitsu-laptop: break up complex loop condition

[MichaÅ KÄpieÅ]

The loop condition in acpi_fujitsu_hotkey_release() includes an
assignment, a four-argument function call and a comparison, making it
hard to read.  Separate the assignment from the comparison to improve
readability.
