Lanqing Liu 125dd8c48b serial: sprd: Fix a dereference warning 
commit efc176929a upstream.

We should validate if the 'sup' is NULL or not before freeing DMA
memory, to fix below warning.

"drivers/tty/serial/sprd_serial.c:1141 sprd_remove()
 error: we previously assumed 'sup' could be null (see line 1132)"

Fixes: f4487db58e ("serial: sprd: Add DMA mode support")
