firmware: arm_ffa: Fix the size of the allocation in ffa_partitions_cleanup()

JIRA: https://issues.redhat.com/browse/RHEL-102691

    Arry of pointer to struct ffa_dev_part_info needs to be allocated to
    fetch the pointers stored in XArray. However, currently we allocate the
    entire structure instead of just pointers.

    Fix the allocation size. This will also eliminate the below Smatch
    istatic checker warning:

       |   drivers/firmware/arm_ffa/driver.c:1251 ffa_partitions_cleanup()
       |   warn: double check that we're allocating correct size: 8 vs 88
