fsl/fman: Free init resources on KeyGen failure in fman_init()

Browse Source 
commit d288efa2b9 upstream.

fman_muram_alloc() allocates initialization resources before
initializing the KeyGen block. If keygen_init() fails, the
function returns -EINVAL directly and leaves those resources
allocated. Free the initialization resources before returning
from the KeyGen failure path.
