Win32: removed attempt to use a drive letter in ngx_fs_bsize(). Just a drive letter might not correctly represent file system being used, notably when using symlinks (as created by "mklink /d"). As such, instead of trying to call GetDiskFreeSpace() with just a drive letter, we now always use GetDiskFreeSpace() with full path. Further, it looks like the code to use just a drive letter never worked, since it tried to test name[2] instead of name[1] to be ':'.
