xtensa: remove free_initrd_mem
The xtensa free_initrd_mem() verifies that initrd is mapped and then
frees its memory using free_reserved_area().
The initrd is considered mapped when its memory was successfully reserved
with mem_reserve().
Resetting initrd_start to 0 in case of mem_reserve() failure allows to
switch to generic free_initrd_mem() implementation.
