ext4: Initialize timestamps limits
ext4 has different overflow limits for max filesystem
timestamps based on the extra bytes available.
The timestamp limits are calculated according to the
encoding table in
a4dad1ae24f85i(ext4: Fix handling of extended tv_sec):
* extra msb of adjust for signed
* epoch 32-bit 32-bit tv_sec to
* bits time decoded 64-bit tv_sec 64-bit tv_sec valid time range
* 0 0 1 -0x80000000..-0x00000001 0x000000000 1901-12-13..1969-12-31

Note that the time limits are not correct for deletion times.
Added a warn when an inode cannot be extended to incorporate an
extended timestamp.
