docs: hugetlbpage.rst: fix some warnings

Some new command line parameters were added at hugetlbpage.rst.
Adjust them in order to properly parse that part of the file,
avoiding those warnings:

        hugepagesz can only be specified once on the command line for a

+       Specify the number of huge pages to preallocate.  This typically
        follows a valid hugepagesz or default_hugepagesz parameter.  However,
        if hugepages is the first or only hugetlb command line parameter it
        implicitly specifies the number of huge pages of default size to
        allocate.  If the number of huge pages of default size is implicitly
        specified, it can not be overwritten by a hugepagesz,hugepages
        parameter pair for the default size.

        will result in 256 2M huge pages being allocated and a warning message
        indicating that the hugepages=512 parameter is ignored.  If a hugepages
        parameter is preceded by an invalid hugepagesz parameter, it will
        be ignored.
-default_hugepagesz - Specify the default huge page size.  This parameter can
+default_hugepagesz
+       pecify the default huge page size.  This parameter can
        only be specified once on the command line.  default_hugepagesz can
        optionally be followed by the hugepages parameter to preallocate a
        specific number of huge pages of default size.  The number of default
        sized huge pages to preallocate can also be implicitly specified as
        mentioned in the hugepages section above.  Therefore, on an

        will all result in 256 2M huge pages being allocated.  Valid default
        huge page size is architecture dependent.
