kexec output message misses the prefix "kexec", when Dave Young split
the kexec code. Now, we use file name as the output message prefix.
Currently, the format of output message:
[ 140.290795] SYSC_kexec_load: hello, world
[ 140.291534] kexec: sanity_check_segment_list: hello, world
Ideally, the format of output message:
[ 30.791503] kexec: SYSC_kexec_load, Hello, world
[ 79.182752] kexec_core: sanity_check_segment_list, Hello, world
Remove the custom prefix "kexec" in output message.

v3:
- Move the macro to the top of the c file
v2:
- Use KBUILD_MODNAME as prefix, instead of custom string "kexec"
