Alan Coopersmith 6c06c268ad Skip damage calls if DamageCreate fails in exa functions 
Fixes parfait errors such as:
   Null pointer dereference (CWE 476): Write to null pointer pDamage
        at line 1833 of miext/damage/damage.c in function 'DamageRegister'.
          Function DamageCreate may return constant 'NULL' at line 1775,
              called at line 232 of exa/exa_migration_mixed.c
              in function 'exaPrepareAccessReg_mixed'.
          Constant 'NULL' passed into function DamageRegister,
              argument pDamage, from call at line 237.
          Null pointer introduced at line 1775 of miext/damage/damage.c
              in function 'DamageCreate'.
   Null pointer dereference (CWE 476): Write to null pointer pDamage
        at line 1833 of miext/damage/damage.c in function 'DamageRegister'.
          Function DamageCreate may return constant 'NULL' at line 1775,
              called at line 104 of exa/exa_mixed.c
              in function 'exaCreatePixmap_mixed'.
          Constant 'NULL' passed into function DamageRegister,
              argument pDamage, from call at line 109.
          Null pointer introduced at line 1775 of miext/damage/damage.c
              in function 'DamageCreate'.

Checks are similar to handling results of other calls to DamageCreate.
