[PATCH 1/2] Revert "Bluetooth: Fix passing NULL to PTR_ERR"

[Paul Menzel]

This reverts commit 266191aa8d14b84958aaeb5e96ee4e97839e3d87, so that
commit 81be03e026dc ("Bluetooth: RFCOMM: Replace use of memcpy_from_msg
with bt_skb_sendmmsg"), introducing a regression, can be reverted.

[PATCH 2/2] Revert "Bluetooth: RFCOMM: Replace use of memcpy_from_msg with bt_skb_sendmmsg"

[Paul Menzel]

This reverts commit 81be03e026dc0c16dc1c64e088b2a53b73caa895.

Since the commit, transferring files greater than some bytes to the
Nokia N9 (MeeGo) or Jolla (Sailfish OS) is not possible anymore.

We would be much better off with the explanation on why it is causing
a regression on these, is there an error? On top of that we can avoid
such regressions by introducing a test to rfcomm-tester to transfer
big PDUs.

Would you please create a github issue
(https://github.com/bluez/bluez/issues/) and attach the btmon trace so
we can check what is the error, you might as well attach the obexd
logs.
