mmc: sdio_uart: fix xmit_fifo leak when the port table is full

In the Linux kernel, the following vulnerability has been resolved:

mmc: sdio_uart: fix xmit_fifo leak when the port table is full

sdio_uart_add_port() allocates the transmit fifo before claiming a
slot in sdio_uart_table[].  When all UART_NR slots are taken, it
returns -EBUSY with the fifo still allocated, but the probe error
path only kfree()s the port, leaking the transmit fifo.

Free the fifo in the failure path of sdio_uart_add_port() itself so
the function retains nothing on error.
