Zeng Heng 5834a3a98c pinctrl: devicetree: fix null pointer dereferencing in pinctrl_dt_to_map 
[ Upstream commit 91d5c5060e ]

Here is the BUG report by KASAN about null pointer dereference:

BUG: KASAN: null-ptr-deref in strcmp+0x2e/0x50
Read of size 1 at addr 0000000000000000 by task python3/2640
Call Trace:
 strcmp
 __of_find_property
 of_find_property
 pinctrl_dt_to_map

kasprintf() would return NULL pointer when kmalloc() fail to allocate.
So directly return ENOMEM, if kasprintf() return NULL pointer.

Fixes: 57291ce295 ("pinctrl: core device tree mapping table parsing support")
