Jeff Mahoney 1d965fe0eb reiserfs: fix warnings with gcc 4.4
Several code paths in reiserfs have a construct like:

 if (is_direntry_le_ih(ih = B_N_PITEM_HEAD(src, item_num))) ...

which, in addition to being ugly, end up causing compiler warnings with
gcc 4.4.0.  Previous compilers didn't issue a warning.

fs/reiserfs/do_balan.c:1273: warning: operation on `aux_ih' may be undefined
fs/reiserfs/lbalance.c:393: warning: operation on `ih' may be undefined
fs/reiserfs/lbalance.c:421: warning: operation on `ih' may be undefined
fs/reiserfs/lbalance.c:777: warning: operation on `ih' may be undefined

I believe this is due to the ih being passed to macros which evaluate the
argument more than once.  This is old code and we haven't seen any
problems with it, but this patch eliminates the warnings.

It converts the multiple evaluation macros to static inlines and does a
preassignment for the cases that were causing the warnings because that
code is just ugly.
