I've replaced the hardcoded arithmetic expression for calculating TotalProcs
within the pgaio_uring_shmem_init() with a call to the dedicated
pgaio_uring_procs() function.
This can make the code's intent clearer. Simplifies future modifications
to the calculation, as it only needs to be updated in one place.

Replace the direct arithmetic expression for TotalProcs with a call to
pgaio_uring_procs() in pgaio_uring_shmem_init().
