ocxl: remove set but not used variables 'tid' and 'lpid'

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
  drivers/misc/ocxl/link.c:187:6: warning: variable 'lpid' set but not used

They are never used and can be removed.
