soc: qcom: fix to avoid memory allocation failures

Currenlty wdsp_glink_write() API allocates 256KB buffer and free
after it is transferred to glink. But this may result in memory
allocation failures in low memory situations. Fix this issue by
allocating the required size and validate it to avoid overflow.
