isofs: fix up CodingStyle
fs/isofs/* had a bunch of CodingStyle issues.
* Indentation was a mix of spaces and tabs
* "int * foo" instead of "int *foo"
* "while ( foo )" instead of "while (foo)"
* if (foo) blah; on one line instead of two
* Missing printk KERN_ levels
* lots of trailing whitespace
* lines >80 columns changed to wrap.
* Unnecessary prototype removed by shuffling code order in C file.
Should be no functional changes other than slight size increase due to
printk changes. Further improvement possible, but this is a start..
