target: fix messages and return values of failed op because not halted

Browse Source 
Lot of messages was logged as LOG_WARNING, but the operation failed
immediately. Sometimes no error message was logged at all.
Add missing messages, change warnings to errors.

Sometimes ERROR_TARGET_INVALID was returned. Some command handlers
returned ERROR_OK! Always return ERROR_TARGET_NOT_HALTED.

While on it use LOG_TARGET_ERROR() whenever possible.
Prefix command_print() message with 'Error:' to get closer
to LOG_TARGET_ERROR() variant.

Error message was not added to get() and set() methods of
struct xxx_reg_type - the return value is properly checked and a message
is logged by the caller in case of ERROR_TARGET_NOT_HALTED.
