rproc_alloc_firmware() (called by rproc_alloc()) can allocate
rproc->firmware using kstrdup_const() and therefore should be freed
using kfree_const(); however, rproc_set_firmware() frees it using the
simple kfree(). This causes a kernel oops if a constant string is passed
to rproc_alloc() and rproc_set_firmware() is subsequently called.
Fix the above issue by using kfree_const() to free rproc->firmware in
rproc_set_firmware().
