ath10k: fix latency issue for QCA988x

Bad latency is found on QCA988x, the issue was introduced by
commit 4504f0e5 ("ath10k: sdio: workaround firmware UART
pin configuration bug"). If uart_pin_workaround is false, this
change will set uart pin even if uart_print is false.

Tested HW: QCA9880
Tested FW: 10.2.4-1.0-00037

Fixes: 4504f0e5 ("ath10k: sdio: workaround firmware UART pin configuration bug")
