platform/x86: panasonic-laptop: Allocate 1 entry extra in the sinf array
Some DSDT-s have an off-by-one bug where the SINF package count is
one higher than the SQTY reported value, allocate 1 entry extra.
Also make the SQTY <-> SINF package count mismatch error more verbose
to help debugging similar issues in the future.
This fixes the panasonic-laptop driver failing to probe() on some
devices with the following errors:
[ 3.958887] SQTY reports bad SINF length SQTY: 37 SINF-pkg-count: 38
[ 3.958892] Couldn't retrieve BIOS data
[ 3.983685] Panasonic Laptop Support - With Macros: probe of MAT0019:00 failed with error -5
Fixes: 709ee531c153 ("panasonic-laptop: add Panasonic Let's Note laptop extras driver v0.94")
