Linux-6.10: define a wrapper for vmalloc
    
    The Linux 6.10 commit:
        "mm: vmalloc: enable memory allocation profiling" (88ae5fb755)
    changed vmalloc from a function to a wrapper macro.
    
    This change results in build errors:
        "error: implicit declaration of function ‘vmalloc’; did you mean
           ‘kmalloc’? [-Werror=implicit-function-declaration]"
    
    when vmalloc is passed as a parameter to the afs_atomlist_create() and
    afs_lhash_create() functions.
    
    Add a little wrapper function around vmalloc() to use for the parameter
    to afs_atomlist_create() and afs_lhash_create().
    
    Note: A configure test was not needed for this change since the name
    and functionality of Linux's vmalloc did not change.
