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..
