I am using

xfs-cmds/xfstests/dmapi/src/suite1/cmd/path_to_handle

and the relative path passed as an argument is directly given to 
dm_path_to_handle().
The current working directory
I can't really explain why it doesn't work in your case. Here is an 
example of a directory
path to handle I get:

emu:/home/vapo/isms/xfs-cmds/xfstests/dmapi/src/suite1/cmd # 
./path_to_handle /mnt/scratch1/dmapi
5d1111a90e4800000e0000006e0000008300000000000000
emu:/home/vapo/isms/xfs-cmds/xfstests/dmapi/src/suite1/cmd # 
./path_to_handle ../../../../../../../../../mnt/scratch1/dmapi
5d1111a90e4800000e0000006e0000008300000000000000
emu:/home/vapo/isms/xfs-cmds/xfstests/dmapi/src/suite1/cmd # cd /
emu:/ # 
/home/vapo/isms/xfs-cmds/xfstests/dmapi/src/suite1/cmd/path_to_handle 
../../../../../../../../../mnt/scratch1/dmapi
5d1111a90e4800000e0000006e0000008300000000000000
