x86, boot: correct sanity checks in boot/compressed/misc.c
arch/x86/boot/compressed/misc.c contains several sanity checks on the
output address. Correct constraints that are no longer correct:
- the alignment test should be MIN_KERNEL_ALIGN on both 32 and 64
bits.
- the 64 bit maximum address was set to 2^40, which was the limit of
one specific x86-64 implementation. Change the test to 2^46, the
current Linux limit, and at least try to test the end rather than
the beginning.
- for non-relocatable kernels, test against LOAD_PHYSICAL_ADDR on both
32 and 64 bits.
[ Impact: fix potential boot failure due to invalid tests ]
