drm/gem-shmem: revert the 8-byte alignment constraint

Browse source

Using drm_mode_size_dumb() to compute the size of dumb buffers introduced
an 8-byte alignment constraint on the pitch that wasn’t present before.
Let’s remove this constraint, which isn’t necessarily required and may
cause buffers to be allocated larger than needed.
