Downgrade fatal to warning in linux_async
This commit downgrades a fatal error to a warning in linux_async.
linux_async is called from two different places in gdbserver:
Via target_async from handle_accept_event. The argument
is always zero, so the warning will never be printed here.
Via start_non_stop from handle_general_set. This prints
its own error message to stderr on failure, which will
be preceded by the warning if it is emitted.
gdb/gdbserver/ChangeLog:
* linux-low.c (linux_async): Replace fatal with warning.
Tidy up and return.
(linux_start_non_stop): Return -1 if linux_async failed.
