vfs: kernel_flock and named streams
Streams implementing VFS modules may implement streams in a way that the
fsp will have the basefile open in the fsp fd, so lacking a distinct fd
for the stream, kernel_flock will apply on the basefile which is
wrong. The actual check is deffered to the VFS module implementing the
kernel_flock call.
