[PATCH v1 3/5] misc: fastrpc: Fix initial memory allocation for Audio PD memory pool

[Ekansh Gupta]

The initially allocated memory is not properly included in the pool,
leading to potential issues with memory management. Set the number
of pages to one to ensure that the initially allocated memory is
correctly added to the Audio PD memory pool.
