ath10k: sdio: use same endpoint id for all packets in a bundle

[ Upstream commit 679e1f07c86221b7183dd69df7068fd42d0041f6 ]

All packets in a bundle should use the same endpoint id as the
first lookahead.

This matches how things are done is ath6kl, however,
this patch can theoretically handle several bundles
in ath10k_sdio_mbox_rx_process_packets().

Without this patch we get lots of errors about invalid endpoint id:

ath10k_sdio mmc2:0001:1: invalid endpoint in look-ahead: 224
ath10k_sdio mmc2:0001:1: failed to get pending recv messages: -12
ath10k_sdio mmc2:0001:1: failed to process pending SDIO interrupts: -12
