UART: Fix maybe-uninitialized diagnostic
The following error occurs when building with gcc 5.4.1 (debian stretch):
common-hal/busio/UART.c:104:83: error: 'sercom_index' may be used uninitialized in this function [-Werror=maybe-uninitialized]
sercom_insts[rx->sercom[j].index]->USART.CTRLA.bit.ENABLE == 0) ||
It may be related to the addition of rx-only UARTs; gcc is unable
to infer the intended relationship between have_tx and sercom_index
being set (I am still not entirely confident of it myself)
