Fix creating bogus mem reqs when commit is stalled
...
When commit stage is stalled, LSU ready is deasserted for mem writes
since stores commit immediately; however, the same was not applied to
valid, creating duplicate memory write requests. Fix by guarding both
ready and valid properly.

Fix fence by disallowing x-initialization instead of all-0 mask
...
Setting mem_req_mask to all-zero triggers an assertion error in
mem_scheduler. Instead, disallow initialize-by-x in instruction decode
which is the source of x-propagation. Since this seems to only happen
in VCS, define-gate it accordingly.
This reverts commit a15f4fd483

[BUGFIX] Set mem_req_mask to 0 for fence
...
Fence instructions have address field set to X's which propagates to
cache_req_ready, causing issue stalls. Fix this by setting req_mask to all-zero
so that they can be handled unaffected by x-propagation.
Setting req_valid to 0 does not fix the problem because the LSU only commits
instructions when they have a matching response coming back.
