iommu/tegra241-cmdqv: Simplify deinit flow in tegra241_cmdqv_remove_vintf()

The current flow of tegra241_cmdqv_remove_vintf() is:
 1. For each LVCMDQ, tegra241_vintf_remove_lvcmdq():
    a. Disable the LVCMDQ HW
    b. Release the LVCMDQ SW resource
 2. For current VINTF, tegra241_vintf_hw_deinit():
    c. Disable all LVCMDQ HWs
    d. Disable VINTF HW

Obviously, the step 1.a and the step 2.c are redundant.

Since tegra241_vintf_hw_deinit() disables all of its LVCMDQ HWs, it could
simplify the flow in tegra241_cmdqv_remove_vintf() by calling that first:
 1. For current VINTF, tegra241_vintf_hw_deinit():
    a. Disable all LVCMDQ HWs
    b. Disable VINTF HW
 2. Release all LVCMDQ SW resources

Drop tegra241_vintf_remove_lvcmdq(), and move tegra241_vintf_free_lvcmdq()
as the new step 2.
