"get partial object" doesn't work

[kolAflash]

Looks like "get partial object" isn't working. Even if simple-mtpfs is detecting that capability.

---

System: openSUSE 42.2

Tested simple-mtpfs versions (same results):

• 0.2 - by openSUSE 42.2
• 0.3 - Compiled by me, including also self compiled libmtp-1.1.13. Both (simple-mtpfs and libmtp) compiled with the following (is that enough/correct!?): CFLAGS=-DHAVE_LIBMTP_CHECK_CAPABILITY=1 CPPLAGS=-DHAVE_LIBMTP_CHECK_CAPABILITY=1 CXXFAGS=-DHAVE_LIBMTP_CHECK_CAPABILITY=1 ./configure

MTP-Device: Samsung galaxy S4 Mini (i9195), running Android 7.1.1 (LineageOS 14.1).

$ simple-mtpfs --list-devices --verbose
1: SamsungGalaxy models (MTP)
  - can get  partial object: yes
  - can send partial object: yes
  - can edit objects       : yes

Yeah, I know. I need to implement some missing bits. This thing is WIP for now...
