Fixed expanding $STANDARD_INFORMATION with almost-full MFT record 

When setting a security descriptor on an NTFS v1.2 format file in an
NTFS v3.0+ volume, NTFS-3G would migrate $STANDARD_INFORMATION to the
new format, which requires extending its size from 48 to 72 bytes.  If
this happened while the file's MFT record was almost full, and none of
the file's attributes could be made non-resident, and the file did not
have an attribute list attribute, then the operation would unexpectedly
fail with ENOENT.  Fix this by adding an attribute list to the file in
this situation.
