UBI: block: Continue creating ubiblocks after an initialization error

If one ubi volume is corrupted but another is not, it should be
possible to initialize that ubiblock from a kernel commandline which
includes both of them. This patch changes the error handling behavior
in initializing ubiblock to ensure that all parameters are attempted
even if one fails. If there is a failure, it is logged on dmesg.
It also makes error messages more descriptive by including the
name of the UBI volume that failed.

Tested: Formatted ubi volume /dev/ubi5_0 in a corrupt way and
dev/ubi3_0 properly and included "ubi.block=5,0 ubi.block=3,0" on
the kernel command line. At boot, I see the following in the console:
[   21.082420] UBI error: ubiblock_create_from_param: block: can't open volume on ubi5_0, err=-19
[   21.084268] UBI: ubiblock3_0 created from ubi3:0(rootfs)
