Subject: [PATCH] perf probe: Correct error message for non-structure type

perf probe outputs incorrect error message when it is called with
non-existent field on a non-data structure local variable.

<Before>
 # perf probe vfs_read 'count.hoge'
  Fatal: Structure on a register is not supported yet.
 # perf probe vfs_read 'count->hoge'
  Fatal: Semantic error: hoge must be referred by '.'

This corrects the messsage.

<After>
 # perf probe vfs_read 'count.hoge'
  Fatal: count is not a data structure.
 # perf probe vfs_read 'count->hoge'
  Fatal: count is not a data structure.
