fangxinyong 5176fb917a fs/vfs: ftruncate produce EINVAL if fd is not open for writing
As posix spec, ftruncate should produce EBADF or EINVAL error,
if the file descriptor fd is not open for writing.

Change the behavior to be similar to Linux and pass ltp open_posix test:

Gregory Nutt e4652bd3dc Squashed commit of the following:
fs: Add truncate() support for userfs
    fs/unionfs:  Add truncate() support to the unionfs
    fs/tmpfs:  Add ftruncate() support to tmpfs
    syscall/: Add system call support for ftruncate()
    net/route:  Adding ftruncate() support eliminates an issue in file-based routing table management.
    fs:  Add basic framework to support truncate() and ftruncate().  The infrastructure is complete.  Now, however, the actual implementation of ftruncate() will have to be done for each file system.
