wifi: ath10k: Fix an error code problem in ath10k_dbg_sta_write_peer_debug_trigger()

[ Upstream commit c511a9c12674d246916bb16c479d496b76983193 ]

Clang Static Checker (scan-build) warns:

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.
