ext4: fix extent sanity checking code with AGGRESSIVE_TEST

The extents sanity-checking code depends on the ext4_ext_space_*()
functions returning the maximum alloable size for eh_max; however,
when the debugging #ifdef AGGRESSIVE_TEST is enabled to test the
extent tree handling code, this prevents a normally created ext4
filesystem from being mounted with the errors:

Aug 26 15:43:50 bsd086 kernel: [   96.070277] EXT4-fs error (device sda8): ext4_ext_check_inode: bad header/extent in inode #8: too large eh_max - magic f30a, entries 1, max 4(3), depth 0(0)
Aug 26 15:43:50 bsd086 kernel: [   96.070526] EXT4-fs (sda8): no journal found

Bug reported by Akira Fujita.
