caam_keyblob: Fix the caam_jr_enqueue() return value check

Since commit 4d370a103695 ("crypto: caam - change return code
in caam_jr_enqueue function") the caam_jr_enqueue() does not return 0
on success anymore.

The new return value when caam_jr_enqueue() succeeds is
-EINPROGRESS.

Check for both the old and the new return values so that
caam_keyblob can work with old and new kernels.

Tested on a imx7s-warp board running 5.10.76.

A big thanks to Jó Ágila Bitsch for pointing out the caam_jr_enqueue()
return value change.
