- Destroy BOs after releasing the mutex to avoid lock contention
- Use dynamic array with realloc to handle arbitrary number of BOs

Although the value is correct; there is no source of truth between
kernel and userspace. This leads to problems if the kernel has strict
restrictions (such as kernel 6.17 or earlier). The restrictions were
lifted in 6.17.9 and and 6.18, but there is no guarantee userspace is
using this.
So short term this value will be wrong. But on newer kernels the kernel
will communicate the right size and rocr-runtime will be adjusted to
use that.
