net: stmmac: fix the crash issue for zero copy XDPTX action

There is a crash issue when running zero copy XDPTX action, the crash log is shown below.

[ 216.122464] Unable to handle kernel paging request at virtual address fffeffff80000000 [ 216.187524] Internal error: Oops: 0000000096000144 [#1] SMP [ 216.301694] Call trace: [ 216.304130] dcachecleanpoc+0x20/0x38 (P) [ 216.308308] dmasyncsinglefordevice+0x1bc/0x1e0 [ 216.313351] stmmacxdpxmitxdpf+0x354/0x400 [ 216.317701] stmmacxdprunprog+0x164/0x368 [ 216.322139] stmmacnapipollrxtx+0xba8/0xf00 [ 216.326576] napipoll+0x40/0x218 [ 216.408054] Kernel panic - not syncing: Oops: Fatal exception in interrupt

For XDPTX action, the xdpbuff is converted to xdpframe by xdpconvertbufftoframe(). The memory type of the resulting xdpframe depends on the memory type of the xdpbuff. For page pool based xdpbuff it produces xdpframe with memory type MEMTYPEPAGEPOOL. For zero copy XSK pool based xdpbuff it produces xdpframe with memory type MEMTYPEPAGEORDER0. However, stmmacxdpxmitback() does not check the memory type and always uses the page pool type, this leads to invalid mappings and causes the crash. Therefore, check the xdpbuff memory type in stmmacxdpxmitback() to fix this issue.
