[PATCH -next] firmware: imx: Add missing return in error path to prevent use-after-free.

[Pankaj Gupta]

After freeing dev_ctx and setting *new_dev_ctx to NULL, the function
continues execution and dereferences dev_ctx, leading to a potential
use-after-free. Return immediately to avoid accessing freed memory.

This appears to have been lost during merge of the original fix.
