hfsplus: fix expand when not enough available space
Fix a bug which is reproduced as follows. Create a file: echo abc > test_file Try to expand the file beyond available space: truncate --size=<size exceeding available space> test_file Since HFS+ does not support file size > allocated size, truncate should fail. However, it ends successfully. The driver returns success despite having been unable to allocate the requested space for the file. Also filesystem check finds an error: Checking catalog file. Incorrect size for file test_file (It should be 469094400 instead of 1000000000) Add a piece of code analogous to code in the fat driver. Now a proper error is returned and filesystem remains consistent.
