Peter Hutterer 0d27fbb67c xkb: fix client-triggerable memory leak in ProcXkbGetKbdByName
CHK_MASK_LEGAL expands to 'return BadValue' when the check fails and
doesn't clean up the already allocated names.keycodes, names.types, etc.

Move the check up so we don't need any cleanup code.

The X server uses this directory to store the compiled version of the
current keymap and/or any scratch keymaps used by clients.  The X server
or some other tool might destroy or replace the files in this directory,
so it is not a safe place to store compiled keymaps for long periods of
time.  The default keymap for any server is usually stored in:
     X<num>-default.xkm
where <num> is the display number of the server in question, which makes
it possible for several servers *on the same host* to share the same
directory.

Unless the X server is modified, sharing this directory between servers on
different hosts could cause problems.
