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

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Currently the success path in function vfio_fsl_mc_reflck_attach is
returning an uninitialized value in variable ret. Fix this by setting
this to zero to indicate success.

Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: f2ba7e8c947b ("vfio/fsl-mc: Added lock support in preparation for interrupt handling")
