accel/habanalabs: use exported size from dma_buf and not from phys_pg_pack

Browse source

The 'exported_size' member in 'struct hl_vm_phys_pg_pack' is used to
keep the exported dma-buf size, to be later used when the buffer is
mapped.
However it is possible that the same phys_pg_pack will be exported more
than once, and independently of when the mapping takes place.
Remove this member from the phys_pg_pack structure, and simply use the
size in the dma-buf object as the exported size when mapping.
