IOMUX: Preserve console list if realloc() fails
It's realloc() 101 to avoid `foo = realloc(foo, ...);` call
due to getting a memory leak.
Actually it's not clear why realloc() has been used here.
If we shrink the array, the memcpy() overwrites it anyway
with the contents of a new array. If it becomes bigger,
same story.
Drop useless realloc() for good and thus preserve console list
in case of failed allocation.
Fixes: 16a28ef219c2 ("IOMUX: Add console multiplexing support.")
