[obv] Unbreak gdbserver build

I run cross a build failure on trunk when testing my approved patches.

gcc -c -g -O2    -I. -I../../../cvs/src/gdb/gdbserver
-I../../../cvs/src/gdb/gdbserver/../../include -Wall
-Wdeclaration-after-statement -Wpointer-arith -Wformat-nonliteral
-Wno-char-subscripts -Werror ../../../cvs/src/gdb/gdbserver/i386-low.c
cc1: warnings being treated as errors
../../../cvs/src/gdb/gdbserver/i386-low.c: In function
../../../cvs/src/gdb/gdbserver/i386-low.c:569: error: âcontrolâ may be
used uninitialized in this function

It is obvious.  Committed.
