vfio/fsl-mc: fix the return of the uninitialized variable ret 

The vfio_fsl_mc_reflck_attach function may return, on success path,
an uninitialized variable. Fix the problem by initializing the return
variable to 0.

Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: f2ba7e8c94 ("vfio/fsl-mc: Added lock support in preparation for interrupt handling")
