perf probe: Use the last field name as the argument name
Set the last field name to the argument name when the argument
is refering a data-structure member.
e.g.
./perf probe --add 'vfs_read file->f_mode'
Add new event:
probe:vfs_read (on vfs_read with f_mode=file->f_mode)
This probe records file->f_mode, but the argument name becomes "f_mode".
This enables perf-trace command to parse trace event format correctly.
