Tomasz Zawadzki 2172c432cf log: simplify SPDK_LOG_REGISTER_COMPONENT 
This patch removes the string from register component.
Removed are all instances in libs or hardcoded in apps.

Starting with this patch literal passed to register,
serves as name for the flag.

All instances of SPDK_LOG_* were replaced with just *
in lowercase.
No actual name change for flags occur in this patch.

Affected are SPDK_LOG_REGISTER_COMPONENT() and
SPDK_*LOG() macros.
