PM: hibernate: Use flexible array for CRC uncompressed buffers

Browse source

The CRC uncompressed buffer pointer array has the same lifetime as
struct crc_data, but it is currently allocated separately.  That adds
another allocation failure path and a matching cleanup branch without
providing any extra flexibility.

Store the pointer array as a flexible array member and allocate it
together with the crc_data using kzalloc_flex().  The array remains
zero-initialized, while the allocation and error handling become
simpler.
