[PATCH] kexec: Add prefix "kexec" to output message

[Minfei Huang]

kexec output message misses the prefix "kexec", when Dave Young split
the kexec code. To keep the same format, add the prefix "kexec" to
output message.

Following is the format of output message now.
[  140.290795] SYSC_kexec_load: hello, world

Ideally, the format of output message likes below.
[  140.291534] kexec: sanity_check_segment_list: hello, world
