platform/x86: sony-laptop: Remove useless comparisons in sony_pic_read_possible_resource()

Browse Source 
Local variable 'p' is initialized by an address
of field of acpi_resource structure, so it does
not make sense to compare 'p' with NULL.

Local variable 'io' is initialized by an address
of field of acpi_resource structure, so it does
not make sense to compare 'io' with NULL.
