workqueue, freezer: unify spelling of 'freeze' + 'able' to 'freezable'

Browse source 
There are two spellings in use for 'freeze' + 'able' - 'freezable' and
'freezeable'.  The former is the more prominent one.  The latter is
mostly used by workqueue and in a few other odd places.  Unify the
spelling to 'freezable'.
