selftests/dma: fix invalid array access in printf
The printf statement attempts to print the DMA direction string using
the syntax 'dir[directions]', which is an invalid array access. The
variable 'dir' is an integer, and 'directions' is a char pointer array.
This incorrect syntax should be 'directions[dir]', using 'dir' as the
index into the 'directions' array. Fix this by correcting the array
access from 'dir[directions]' to 'directions[dir]'.
