ath10k: fix the garage chars in board file name creation
The variant[] string will be valid only if the bdf_ext is set.
The string memory needs to be null-terminated to avoid the undefined garbage
appended by the subsequent board file name creation.
ath10k_pci 0000:04:00.0: failed to fetch board data for
"bus=pci,vendor=168c,device=003e,subsystem-vendor=168c,subsystem-device=3363��P�����"
from ath10k/QCA6174/hw3.0/board-2.bin
Fixes: f2593cb1b291 ("ath10k: Search SMBIOS for OEM board file extension")
