Fixes gcc '-Wunused-but-set-variable' warning:

drivers/misc/ocxl/link.c: In function 'xsl_fault_handler':
drivers/misc/ocxl/link.c:187:17: warning: variable 'tid' set but not used [-Wunused-but-set-variable]
drivers/misc/ocxl/link.c:187:6: warning: variable 'lpid' set but not used [-Wunused-but-set-variable]

They are never used and can be removed.
