[PATCH v1] drbd: Fix typos in the comment

[Yan Zhen <yanzhen@vivo.com>]

Correctly spelled comments make it easier for the reader to understand
the code.

Fix typos:
'mutliple' ==> 'multiple',
'droped' ==> 'dropped',
'Suprisingly' ==> 'Surprisingly',
'chage' ==> 'change',
'typicaly' ==> 'typically',
'progres' ==> 'progress',
'catched' ==> 'caught',
'protocoll' ==> 'protocol',
'stroage' ==> 'storage',
'independend' ==> 'independent'.
