Daeho Jeong 97e4f47993 f2fs: support non-4KB block size without packed_ssa feature 
commit e48e16f3e3 upstream.

Currently, F2FS requires the packed_ssa feature to be enabled when
utilizing non-4KB block sizes (e.g., 16KB). This restriction limits
the flexibility of filesystem formatting options.

This patch allows F2FS to support non-4KB block sizes even when the
packed_ssa feature is disabled. It adjusts the SSA calculation logic to
correctly handle summary entries in larger blocks without the packed
layout.
