soc: qcom: memory_dump_v2: use kmemleak_not_leak for mem dump's app table

Table (of type msm_dump_table) is virtual address for app's base
table of memdump, which is converted to physical address and
holds it in the memdump.table_phys. This memory is not intended
to be freed. When kmemleak scans, it can't deduce that the reference
we are holding is via physical address and not virtual address.
Hence, kmemleak will treat this as a leak as it can't find
a reference to this variable. Suppress this by using
kmemleak_not_leak API.
