scsi: ufs: mediatek: Fix out-of-bounds access in MCQ IRQ mapping

Address a potential out-of-bounds access issue when accessing
'host->mcq_intr_info[q_index]'. The value of 'q_index' might exceed the
valid array bounds if 'q_index == nr'.  Correct condition to 'q_index >=
nr' to prevent accessing invalid memory.
