powerpc/ucc_geth: deal with a compile warning

deal with a compile warning: comparison between
'enum qe_fltr_largest_external_tbl_lookup_key_size'
and 'enum qe_fltr_tbl_lookup_key_size'

the code:
	"if (ug_info->largestexternallookupkeysize ==
	     QE_FLTR_TABLE_LOOKUP_KEY_SIZE_8_BYTES)"
is warned because different enum, so modify it.

	"enum qe_fltr_largest_external_tbl_lookup_key_size
	             largestexternallookupkeysize;

	enum qe_fltr_tbl_lookup_key_size {
		 QE_FLTR_TABLE_LOOKUP_KEY_SIZE_8_BYTES
			 = 0x3f,         /* LookupKey parsed by the Generate LookupKey
					    CMD is truncated to 8 bytes */
		 QE_FLTR_TABLE_LOOKUP_KEY_SIZE_16_BYTES
			 = 0x5f,         /* LookupKey parsed by the Generate LookupKey
					    CMD is truncated to 16 bytes */
	 };

	 /* QE FLTR extended filtering Largest External Table Lookup Key Size */
	 enum qe_fltr_largest_external_tbl_lookup_key_size {
		 QE_FLTR_LARGEST_EXTERNAL_TABLE_LOOKUP_KEY_SIZE_NONE
			 = 0x0,/* not used */
		 QE_FLTR_LARGEST_EXTERNAL_TABLE_LOOKUP_KEY_SIZE_8_BYTES
			 = QE_FLTR_TABLE_LOOKUP_KEY_SIZE_8_BYTES,        /* 8 bytes */
		 QE_FLTR_LARGEST_EXTERNAL_TABLE_LOOKUP_KEY_SIZE_16_BYTES
			 = QE_FLTR_TABLE_LOOKUP_KEY_SIZE_16_BYTES,       /* 16 bytes */
	 };"
