Initialize `location' in gdbpy_decode_line

Browse Source 
BuildBot flagged an uninitialized variable coming from one of the patches
in my recently committed locations/explicit patchset.

The following patch fixes this.

gdb/ChangeLog

	* python/python.c (gdbpy_decode_line): Initialize `location' to NULL
	and only call decode_line_1 when it is non-NULL.
