glsl: remove redundant record_compare check when linking globals

Browse Source 
Unnamed struct types are now equal across stages based on the fields they
contain, so overriding the type to make sure names match has become
unnecessary.

The check was originally introduced in commit 955c93dc08 ("glsl: Match
unnamed record types across stages.")

v2: clarify the commit message
