IB/uverbs: Always use the attribute size provided by the user
This fixes several bugs around the copy_to/from user path:
- copy_to used the user provided size of the attribute
and could copy data beyond the end of the kernel buffer into
userspace.
- copy_from didn't know the size of the kernel buffer and
could have left kernel memory unexpectedly un-initialized.
- copy_from did not use the user length to determine if the
attribute data is inlined or not.
