Subject: [PATCH] XArray: handle XA_FLAGS_ACCOUNT in xas_split_alloc

Commit 7b785645e8f1 ("mm: fix page cache convergence regression")
added support of new XA_FLAGS_ACCOUNT flag into all Xarray allocation
functions. Later commit 8fc75643c5e1 ("XArray: add xas_split")
introduced xas_split_alloc() but missed about XA_FLAGS_ACCOUNT
processing.
