libceph: bump CEPH_MSG_MAX_DATA_LEN
commit 94e6992bb560be8bffb47f287194adf070b57695 upstream.
If the read is large enough, we end up spinning in the messenger:
libceph: osd0 192.168.122.1:6801 io error
libceph: osd0 192.168.122.1:6801 io error
libceph: osd0 192.168.122.1:6801 io error
This is a receive side limit, so only reads were affected.
