ath10k: fix documentation in ath10k_wow_convert_8023_to_80211()

With W=1 there's a warning:

drivers/net/wireless/ath/ath10k/wow.c:93: warning: Function parameter or member 'new' not described in 'ath10k_wow_convert_8023_to_80211'
drivers/net/wireless/ath/ath10k/wow.c:93: warning: Function parameter or member 'old' not described in 'ath10k_wow_convert_8023_to_80211'

Fix it by changing the documentation marker '/**' to a normal code comment.
While at it, clean up the line wrapping.
