Fix any_thread_of_inferior
Running gdb-term.exp against gdbserver with "maint set target-non-stop on", runs into this: [infrun] fetch_inferior_event: exit [infrun] fetch_inferior_event: enter /home/pedro/gdb/binutils-gdb/src/gdb/thread.c:72: internal-error: thread_info* inferior_thread(): Assertion `current_thread_ != nullptr' failed. A problem internal to GDB has been detected, further debugging may prove unreliable. This is a bug, please report it. For instructions, see: <https://www.gnu.org/software/gdb/bugs/>.

The bug is that any_thread_of_inferior incorrectly assumes that there's always a selected thread. This fixes it. gdb/ChangeLog: * thread.c (any_thread_of_inferior): Check if there's a selected thread before calling inferior_thread(). Change-Id: Ica4b9ec746121a7a7c22bef09baea72103b3853d
