[PATCH] ntfs: fix incorrect MFT record pointer passed to ntfs_attr_record_resize

[Hongling Zeng]

ntfs_new_attr_flags() passes the wrong MFT record to ntfs_attr_record_resize().
When the attribute is in an extent record, ctx->mrec points to the extent
but the function receives the base record pointer m, causing incorrect
size calculations in memmove.

Fix by passing ctx->mrec (the actual MFT record containing the attribute)
instead of m (the base MFT record) to ntfs_attr_record_resize().
