bnxt_en: Add mem_valid bit to struct bnxt_ctx_mem_type

Browse Source 
Add a new bit to struct bnxt_ctx_mem_type to indicate that host
memory has been successfully allocated for this context memory type.
In the next patches, we'll be adding some additional context memory
types for FW debugging/logging.  If memory cannot be allocated for
any of these new types, we will not abort and the cleared mem_valid
bit will indicate to skip configuring the memory type.
