tee: optee: fix device enumeration error handling

[ Upstream commit 03212e347f9443e524d6383c6806ac08295c1fb0 ]

Prior to this patch in optee_probe() when optee_enumerate_devices() was
called the struct optee was fully initialized. If
optee_enumerate_devices() returns an error optee_probe() is supposed to
clean up and free the struct optee completely, but will at this late
stage need to call optee_remove() instead. This isn't done and thus
freeing the struct optee prematurely.

With this patch the call to optee_enumerate_devices() is done after
optee_probe() has returned successfully and in case
optee_enumerate_devices() fails everything is cleaned up with a call to
optee_remove().
