Anton Blanchard cd32e2dcc9 powerpc: Fix bad NULL pointer check in udbg_uart_getc_poll() 
We have some code in udbg_uart_getc_poll() that tries to protect
against a NULL udbg_uart_in, but gets it all wrong.

Found with the LLVM static analyzer (scan-build).

Fixes: 309257484c ("powerpc: Cleanup udbg_16550 and add support for LPC PIO-only UARTs")
