USB: fsl_qe_udc: Check for muram allocation errors

The QE UDC doesn't check for cpm_muram_alloc() return values, this
might cause all sorts of misbehaviour when cpm_muram_alloc() failed
to allocate the muram memory.

While at at, change few dev_dbg() calls to dev_err(), so that the
driver would not die silently.
