sony-laptop: Fix handling sony_nc_hotkeys_decode result

Browse source

sony_nv_hotkeys_decode can return a negative value. real_ev is a u32 variable.
The check for real_ev > 0 is incorrect.

Use an intermediate ret variable.

The problem has been detected using proposed semantic patch
scripts/coccinelle/tests/assign_signed_to_unsigned.cocci [1].
