[PATCH 310/379][SRU][OEM-5.6] ath11k: fix undefined reference to 'ath11k_debugfs_htt_ext_stats_handler'

[You-Sheng Yang]

From: Kalle Valo <kvalo at codeaurora.org>

BugLink: https://bugs.launchpad.net/bugs/1879633

kbuild bot reported than link fails when CONFIG_ATH11K_DEBUGFS is disabled:

drivers/net/wireless/ath/ath11k/dp_rx.c:1662: undefined reference to `ath11k_debugfs_htt_ext_stats_handler'

This was because I had missed to move the static inline version of the function
(which are used when CONFIG_ATH11K_DEBUGFS is disabled) to debufs_htt_stats.h.
Also move ath11k_debugfs_htt_stats_req() at the same time. And create a stub
also for ath11k_debugfs_htt_stats_init() for consistency, even if it's not
needed.
