hfsplus: fix HFSPLUS_SB calling convention
HFSPLUS_SB doesn't return a pointer to the hfsplus-specific superblock
information like all other FOO_SB macros, but dereference the pointer in a way
that made it look like a direct struct derefence. This only works as long
as the HFSPLUS_SB macro is used directly and prevents us from keepig a local
hfsplus_sb_info pointer. Fix the calling convention and introduce a local
sbi variable in all functions that use it constantly.
