[PATCH 1/5] gdb: add inferior parameter to target_current_description

[Simon Marchi <simon.marchi@efficios.com>]

From: Simon Marchi <simon.marchi@polymtl.ca>

Make target_current_description not dependent on the current inferior on
entry.  Update all callers to pass the current inferior, so no change in
behavior is expected.
