Concern on bugs in vmamba_checks.py

[BaophanN]

In the file classification/models/vmamba_checks.py, there is these lines:

from vmamba import CrossScan, CrossMerge, CrossScan_Ab_1direction, CrossMerge_Ab_1direction, CrossScan_Ab_2direction, CrossMerge_Ab_2direction, getCSM
from vmamba import CrossScanTriton, CrossMergeTriton, CrossScanTriton1b1

However, the implementation of the above module does not exist in vmamba.py file in the same folders.

Those functions are all deprecated, and even the file vmamba_check.py is now useless. I'll consider delete it in the future.
