Some miscellaneous fixes

[maddyscientist]

This is a hotfix PR, nothing too controversial:

• Fixes warnings with GCC 13 as reported by @bjoo
• Fixes QUDA_REORDER_LOCATION=CPU (closes #1466)
• Improves robustness when dealing with nSpin=1 and nSpin=2 fields (only set default gamma basis for nSpin=4 fields to UKQCD basis)
• Improve user experience with clover fermions: always compute the clover field trace log and report if the trace log is not a number (which is symptomatic of invalid parameters)
