misc: enclosure: Fix some kerneldoc anomalies

Firstly some missing function argument documentation, then some
whch are present, but are incorrectly named.

Fixes the following W=1 kernel build warnings:

 drivers/misc/enclosure.c:283: warning: Excess function parameter 'num' description in 'enclosure_component_alloc'
 drivers/misc/enclosure.c:363: warning: Function parameter or member 'component' not described in 'enclosure_add_device'
 drivers/misc/enclosure.c:363: warning: Excess function parameter 'num' description in 'enclosure_add_device'
