f2fs: fix 446 coding style warnings in f2fs.h
1) Nine coding style warnings below have been resolved:
"Missing a blank line after declarations"
2) 435 coding style warnings below have been resolved:
"function definition argument 'x' should also have an identifier name"
3) Two coding style warnings below have been resolved:
"macros should not use a trailing semicolon"
