vfs_bio_awrite() was unconditionally locking a buffer without checking
for races, potentially resulting in the wrong buffer, an invalid buffer,
or a recently replaced buffer being written out. Change the call semantics
to require a locked buffer to be passed into the function rather then
locking the buffer in the function.
