cifs: Remove duplicate struct reparse_symlink_data and SYMLINK_FLAG_RELATIVE

In file common/smb2pdu.h is defined struct reparse_symlink_data_buffer
which is same as struct reparse_symlink_data and is used in the whole code.
So remove duplicate struct reparse_symlink_data from client/cifspdu.h.

In file common/smb2pdu.h is defined also SYMLINK_FLAG_RELATIVE constant, so
remove duplication from client/cifspdu.h.
