[PATCH] scripts/gdb: fix 'lx-current' for x86

[Jeff Xie]

When printing the name of the current process, it will report an error:
(gdb) p $lx_current().comm
Python Exception <class 'gdb.error'> No symbol "current_task" in current context.: 
Error occurred in Python: No symbol "current_task" in current context.

Because the commit <e57ef2ed97c1> ("x86: Put hot per CPU variables into a struct") 
changed it.
