hw/ufs: Fix mcq register range check logic
The function ufs_is_mcq_reg() and ufs_is_mcq_op_reg() only evaluated
the range of the mcq_reg and mcq_op_reg offset, which is defined as
a constant. Therefore, it was possible for them to return true
even though the ufs device is configured to not support the mcq.
This could cause ufs_mmio_read()/ufs_mmio_write() to result in
Null-pointer-dereference.
So fix it.
Resolves: #2428
Fixes: 5c079578d2e4 ("hw/ufs: Add support MCQ of UFSHCI 4.0")
