a bug in ramfs_nommu_resize function, passing old size to vmtruncate

It should be pass "newsize" to vmtruncate function to modify the
inode->i_size, while the old size is passed to vmtruncate.

This bug was caught by LTP truncate test case on Blackfin platform.
After it was fixed, the LTP truncate test case passed.
