PNP: ACPI: Fix string truncation warning
LKP reports below warning when building for RISC-V.
drivers/pnp/pnpacpi/core.c:253:17:
warning: 'strncpy' specified bound 50 equals destination
size [-Wstringop-truncation]
This appears to be a valid issue since the destination string may not be
null-terminated.
To fix this, append the NUL explicitly after the strncpy().
