Revert "drm/xe: Force write completion of MI_STORE_DATA_IMM"
This reverts commit 1460bb1fef9ccf7390af0d74a15252442fd6effd.
In all places the MI_STORE_DATA_IMM are not followed by a read of
the same memory address in the same batch buffer and the posted writes
are flushed with PIPE_CONTROL or MI_FLUSH_DW in xe_ring_ops.c functions
so there is no need to set this register.
