#52 Remove extra paren in lib/ext2fs/irel_ma.c.

[Adam Buchbinder]

There's a syntax error in lib/ext2fs/irel_ma.c; it has an extra parenthesis. However, on my configuration, this file isn't built, which may be how this error snuck into the source; I found it with cppcheck.

Patch against current git.
