x86/dumpstack: Avoid uninitlized variable
In some configurations, 'partial' does not get initialized, as shown by
this gcc-8 warning:
arch/x86/kernel/dumpstack.c: In function 'show_trace_log_lvl':
arch/x86/kernel/dumpstack.c:156:4: error: 'partial' may be used uninitialized in this function [-Werror=maybe-uninitialized]
show_regs_if_on_stack(&stack_info, regs, partial);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This initializes it to false, to get the previous behavior in this case.
Fixes: a9cdbe72c4e8 ("x86/dumpstack: Fix partial register dumps")
