bus: mhi: host: Free mhi_buf vector inside mhi_alloc_bhie_table()

Browse Source 
mhi_alloc_bhie_table() starts by allocating a vector of struct mhi_buf
then it allocates a DMA buffer for each element. If allocation fails,
it will free the allocated DMA buffers, but it neglects freeing the
mhi_buf vector.

Avoid memory leaks by freeing the mhi_buf vector on error.
