soc: fsl: cpm1: qmc: Do not use IS_ERR_VALUE() on error pointers

IS_ERR_VALUE() is only meant for pointers.  Fix this by checking for a
negative error value instead, which matches the documented behavior of
devm_qe_muram_alloc() aka devm_cpm_muram_alloc().
While at it, remove the unneeded print in case of a memory allocation
failure, and propagate the returned error code.
