net: tsec: Fix memory leak in error path

Browse Source 
tsec_initialize allocates a private driver structure using malloc.
Should the memory allocation of this private structure fail, the
function execution is aborted with a return 0, but the previously
allocated device structure is never freed, hence leaked.

Free the device structure in the error case.
