ocfs2: less function calls in ocfs2_convert_inline_data_to_extents() after error detection
kfree() was called in a few cases by ocfs2_convert_inline_data_to_extents()
during error handling even if the passed variable "pages" contained a
null pointer.
* Return from this implementation directly after failure detection for
the function call "kcalloc".
* Corresponding details could be improved by the introduction of another
jump label.
