sys/vfs/hammer: Check ronly when overwriting volume header

Check readonly mount before overwriting volume header
with non-NULL data on load/unload.

(hammer volume-add|del ioctls which are the only cases
with non-NULL data do have readonly mount check before
load/unload, so there isn't any issue without ronly==0
but the check should be done here too)
