Subject: [PATCH wireless v2] wifi: ath10k: Fix an error code problem in ath10k_dbg_sta_write_peer_debug_trigger()

Clang Static Checker (scan-build) Warning:
drivers/net/wireless/ath/ath10k/debugfs_sta.c:line 429, column 3
Value stored to 'ret' is never read.

Return 'ret' rather than 'count' when 'ret' stores an error code.
By the way, remove some useless code.

Fixes: ee8b08a1be82 ("ath10k: add debugfs support to get per peer tids log via tracing")
Signed-off-by: Su Hui <suhui@nfschina.com>

v2:
 - remove the initializer change.
