scripts/gdb: fix 'lx-current' for x86
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 e57ef2ed97c1 ("x86: Put hot per CPU variables into a struct")
changed it.
