fix argument for bitmask_snprintf() (stylistic only, code is commented out anyway)

Fix serious bug in bounce buf handling - the EDF_BOUNCEBUF flag needs
...
to be cleared always in edmcadone(), otherwise if there is a write
via bounce buffer followed by read directly to buf, the read operation
would return trashed data (the buf data would get overwritten
by contents of bounce buffer in edmcadone()).
Reset b_resid as necessary when the i/o is done, too.
g/c some unneeded stuff, use lockmgr()-style locking in ed_[un]lock(),
better avoid some deadlocks
These changes make the driver quite a bit more stable. It's actually
reliable enough to be possible to newfs the drive and use it for
read/write filesystem now.

In nfs_loadattrcache(), if checkalias() gives us a new vnode, lock it. This
...
prevents us losing the locked state of the old vnode.
fvdl thinks the old vnode is certain to be locked at this point. I've put in
a KASSERT to be on the safe side.
This seems to fix PR kern/12661.
