wifi: ath10k: Remove the unused function shadow_dst_wr_ind_addr() and ath10k_ce_error_intr_enable()

The function shadow_dst_wr_ind_addr() and ath10k_ce_error_intr_enable()
are defined in the ce.c file, the code calling them has been removed,
so remove these unused functions.

Eliminate the following warnings:
drivers/net/wireless/ath/ath10k/ce.c:80:19: warning: unused function 'shadow_dst_wr_ind_addr'
drivers/net/wireless/ath/ath10k/ce.c:441:20: warning: unused function 'ath10k_ce_error_intr_enable'
