bpf: Fix bpf_seq_read docs for increased buffer size 



Commit af653209 ("bpf: Bump iter seq size to support BTF
representation of large data structures") increased the fixed buffer
size from PAGE_SIZE to PAGE_SIZE << 3, but the docs for the function
didn't get updated at the same time. Update them.

/* bpf_seq_read, a customized and simpler version for bpf iterator.

 * The following are differences from seq_read():

 *  . fixed buffer size (PAGE_SIZE)

 *  . fixed buffer size (PAGE_SIZE << 3)

 *  . assuming NULL ->llseek()

 *  . stop() may call bpf program, handling potential overflow there
