ocfs2: fix shift-out-of-bounds UBSAN bug in ocfs2_verify_volume()

This patch addresses a shift-out-of-bounds error in the
ocfs2_verify_volume() function, identified by UBSAN.  The bug was
triggered by an invalid s_clustersize_bits value (e.g., 1548), which
caused the expression "1 <<
le32_to_cpu(di->id2.i_super.s_clustersize_bits)" to exceed the limits of a
32-bit integer, leading to an out-of-bounds shift.
