BUG#11756869 - 48848: MYISAMCHK DOING SORT RECOVER IN CERTAIN

Browse Source 
CASES RESETS DATA POINTER TO SMAL

ISSUE: Myisamchk doing sort recover
       on a table reduces data_file_length.
       Maximum size of data file decreases,
       lesser number of rows are stored.

SOLUTION: Size of data_file_length is
          fixed to the original length.
