Hans de Goede c54fc405a0 platform/x86: panasonic-laptop: Allocate 1 entry extra in the sinf array 
commit 33297cef31 upstream.

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: 709ee531c1 ("panasonic-laptop: add Panasonic Let's Note laptop extras driver v0.94")
