Apologize for not obeying the email etiquette.
I've updated my linux kernel to 5.17.0-1-MANJARO x86_64. Then I
downloaded the whole package /WCN6855/hw2.0  and cp them into
/lib/firmware/ath11k/ , whilst cp amss.bin and m3.bin to package hw2.0
from WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3 to meet the
demand.
After reboot, the error message changed to:

[    1.167043] systemd[1]: File System Check on Root Device was
skipped because of a failed condition
check (ConditionPathIsReadWrite=!/).
[    2.388084] ath11k_pci 0000:02:00.0: BAR 0: assigned [mem

which I think to be kind of weird, because I remained the exact
board-2.bin file of the repo in the package.
Then i tried to add ath11k & ath11k_pci into blacklist and modprobe
ath9k but it didn't work as supposed. One thing interesting is that
this improved my reboot speed to a big extent, which may also prove
ath11k still has some problems.
