SPECIFIED WITH THE BASEDIR OPTION

Description: The mysql_plugin client attempts to remove any
filename specified to the --basedir option. The problem is 
that if the filename does not end with a slash, it will 
attempt to unlink it, which succeeds for files, but not for 
directories.

Analysis: When we are starting mysql_plugin with basedir 
option and if we are giving path of a file as basedir, it 
deletes that file. It was because it uses a function 
my_delete which unlinks the file path given.

Fix:  As a fix we replace that line using another function 
my_free, which will only free the  pointer which is having 
that file path.
