[SCSI] megaraid: fix kernel-doc
kernel-doc modifications:
- change "@param var" notation to @var;
- change function/description separator from ':' to '-';
- change var/description separator from '-' to ':';
- fix a few doc. typos;
- don't use kernel-doc /** lead-in when the doc. block is not kernel-doc;
- use Linux common */ ending comment format instead of **/;
- use correct function parameter names;
- place function parameters immediately after the function short description;
- place kernel-doc immediately before its function or macro;
