Before pd logging enabled, there is about 1320 bytes for shared meory; after pd logging is enabled and reserved 512 bytes, only around 780 bytes for shared memory. In shared_mem_acquire(), we request 1024(ChUNK_SIZE) while 780 only available. This causes hashing abort and could not boot to RW. BUG=chrome-os-partner:50127 BRANCH=glados TEST=In kunimitsu system, boot to RO and check available shared memory is higher than 1024; system can soft sync, boot to RW.
