ext4: Fix the alloc on close after a truncate hueristic
In an attempt to avoid doing an unneeded flush after opening a (previously non-existent) file with O_CREAT|O_TRUNC, the code only triggered the hueristic if ei->disksize was non-zero. Turns out that the VFS doesn't call ->truncate() if the file doesn't exist, and ei->disksize is always zero even if the file previously existed. So remove the test, since it isn't necessary and in fact disabled the hueristic. Thanks to Clemens Eisserer that he was seeing problems with files written using kwrite and eclipse after sudden crashes caused by a buggy Intel video driver.
