John-Mark Gurney 9d38fd076e address an issue where consumers, like IPsec, can reuse the same
session in multiple threads w/o locking..  There was a single fpu
context shared per session, if multiple threads were using the session,
and both migrated away, they could corrupt each other's fpu context...

This patch adds a per cpu context and a lock to protect it...

It also tries to better address unloading of the aesni module...
The pause will be removed once the OpenCrypto Framework provides a
better method for draining callers into _newsession...

I first discovered the fpu context sharing issue w/ a flood ping over
an IPsec tunnel between two bhyve machines...  The patch in D3015
was used to verify that this fix does fix the issue...
