Fix storage of SP values in DP registers
...
The SFMA was zero-extending the SP value to 65 bits, rather than filling
the upper 32 bits with 1s. This meant that an FSD + FLD of that register
would not restore the value properly.
Also, minor code cleanup.

Avoid spurious D$ assertion failures
...
For the Rocket pipeline, this fix is needless and the problem is that the
assertion is too conservative, but I solved it this way to avoid problems
for other plausible use cases where physical and virtual accesses are
intermixed.
