shmem: shmem_acct_blocks() and shmem_inode_acct_blocks()
By historical accident, shmem_acct_block() and shmem_inode_acct_block()
were never pluralized when the pages argument was added, despite their
complements being shmem_unacct_blocks() and shmem_inode_unacct_blocks()
all along. It has been an irritation: fix their naming at last.
